Three materials, one decision that defines your bathroom
If you’re renovating a bathroom and you’ve moved past the “I want it to look nice” phase to enter “okay, but what exactly do I put on the walls and floor?”, welcome to the three-material dilemma. Microcement, porcelain tile and SPC vinyl are the three options dominating the bathroom renovation market in 2026, and all three have compelling arguments in their favour.
At Bathscape we’ve installed hundreds of square metres of each in renovations across Valencia and surroundings. We know which performs best in each situation, which causes the most issues, which offers the best value for money and which is pure marketing disguised as innovation. And we’re going to share it all, with data and without filters.
Because choosing the wrong material for your bathroom isn’t like choosing the wrong paint colour. You can change the colour in a weekend. The cladding stays with you for 15-25 years. So it’s worth investing 10 minutes to understand the comparison before making a decision.
Microcement: the aesthetic star of the moment
What it actually is
Microcement is a seamless coating (no joints) composed of cement, polymer resins, pigments and additives. It’s applied in layers of 2-3 mm thickness over practically any substrate: existing tiles, mortar, plaster, plasterboard.
Don’t confuse microcement with polished concrete (5-10 cm thick, for industrial floors) or stamped concrete (for exteriors). Microcement is a decorative material applied as a thin render.
Composition and application
The typical microcement application for a bathroom consists of:
- Adhesion primer on the existing substrate
- Fibreglass mesh embedded in the first layer (prevents cracking)
- Base coat of microcement (1-1.5 mm)
- Finish coat of microcement (0.5-1 mm, pigmented)
- Two-component polyurethane sealer (minimum 2 coats, 3 recommended for bathrooms)
The sealer is the key. Without sealer, microcement absorbs water like a sponge (the cementitious base is porous). With sealer, the surface is waterproof. But the sealer wears with use and needs reapplication every 3-5 years. This is a critical data point that many microcement sellers conveniently omit.
Technical data
| Property | Value |
|---|---|
| Total thickness | 2-3 mm |
| Weight per m² | 3-5 kg |
| Compressive strength | 40-55 N/mm² |
| Flexural strength | 8-12 N/mm² |
| Substrate adhesion | > 1.5 N/mm² (with correct primer) |
| Water absorption (with sealer) | < 1% |
| Water absorption (without sealer) | 15-25% |
| Wear resistance | Medium (depends on sealer) |
| Chemical resistance | Medium (sensitive to acids and concentrated bleach) |
| Anti-slip rating | Class 1-2 (without treatment), Class 3 (with anti-slip additive) |
Real advantages
- No joints: The seamless surface is its greatest visual appeal. No grout lines accumulating dirt or breaking aesthetic continuity. A microcement bathroom looks like a monolithic block.
- Applicable over existing tiles: No need to demolish. Microcement is applied directly over ceramic as long as it’s well-adhered and prepared. That saves €800-1,500 in demolition and waste. For more detail on installation over tiles, check our technical guide on installation over ceramics.
- Minimal thickness: 2-3 mm doesn’t modify the floor level or bathroom geometry. Doors don’t rub, sanitary ware doesn’t change position.
- Unlimited colour palette: Pigment is mixed into the mass, so you can have the exact colour you want. From off-white to absolute black, through the full range of greys, earth tones and greens that are so fashionable.
Drawbacks you should know
- Sealer maintenance: You need to reapply sealer every 3-5 years. Cost: €150-300 in product + labour for a standard 5-6 m² bathroom. If you don’t, the microcement absorbs water, stains and develops mould.
- Sensitivity to acidic products: Cleaners with citric acid, vinegar or concentrated bleach attack the sealer and, eventually, the microcement. Neutral products only (pH 6-8).
- Cracking: Microcement can micro-crack if the substrate moves (thermal expansion, building settlement). The fibreglass mesh reduces the risk but doesn’t eliminate it. In old Valencia buildings with wooden beams or joists, we’ve seen microcement crack within the first year.
- Applicator dependency: The quality of the final result depends 70% on the applicator’s skill. Good microcement badly applied is worse than a cheap tile well laid. And truly good applicators are few. If you get quotes from five companies and one comes in at €40/m² while the other four quote €75-90/m², be suspicious of the cheap one.
- Slippery when wet: Polished microcement is slippery when wet. For the shower floor, you need an anti-slip finish (rougher texture + additive in the sealer). The anti-slip finish is harder to clean than the polished one. It’s an unavoidable trade-off.
Microcement pricing (materials + labour, Valencia)
| Item | Price per m² |
|---|---|
| Standard microcement (floor) | €65-90 |
| Standard microcement (wall) | €55-80 |
| Premium microcement (floor, extra finish) | €85-120 |
| Sealer maintenance (every 3-5 years) | €25-50/m² |
Total cost for a 5 m² floor + 12 m² walls bathroom: €1,285-2,410 (not including future maintenance).
Porcelain tile: the unbeatable all-rounder
What it is
Porcelain tile (or porcelain stoneware) is a high-performance ceramic made from clays, feldspars and quartz, pressed at 400-500 kg/cm² and fired at 1,200-1,300 °C. The result is an extremely hard, dense material with virtually zero water absorption.
It is, by far, the most widely used bathroom material in Spain and across Europe. And there are solid reasons for it.
Types of porcelain tile for the bathroom
Glazed porcelain: The surface is a layer of ceramic glaze fired onto the base. Allows high-resolution digital printing (wood, marble, stone, concrete imitation). It’s the most common and versatile type.
Technical porcelain (full-body): Unglazed. The colour and design run through the entire thickness of the piece. If it gets scratched or chipped, it’s not noticeable because the interior is the same as the surface. More resistant but with less aesthetic variety.
Rectified porcelain: After firing, the edges are rectified (cut) with millimetre precision. Allows joints of 1.5-2 mm vs the 3-5 mm of conventional porcelain. The visual result is cleaner and more modern. For more detail, check our article on rectified porcelain and minimal joints.
Large-format porcelain: Pieces of 60x120, 80x160, 120x120 cm or even slabs of 320x160 cm (Laminam, Neolith type). Fewer joints, more continuous appearance. Requires a specialist installer and high-performance adhesive.
Technical data
| Property | Value |
|---|---|
| Thickness | 8-12 mm (standard), 3-6 mm (thin slabs) |
| Weight per m² | 18-25 kg (10 mm thickness) |
| Compressive strength | > 100 N/mm² |
| Flexural strength | 35-55 N/mm² |
| Water absorption | < 0.5% (EN ISO 10545-3 standard) |
| PEI rating (wear resistance) | PEI III-V (III for wall, IV-V for floor) |
| Anti-slip rating | Class 1 (polished) to Class 3 (textured) |
| Chemical resistance | Excellent (Class A or B per EN ISO 10545-13) |
| Frost resistance | Yes (due to low absorption) |
| Mohs hardness | 6-7 (cannot be scratched with steel) |
Advantages
- Legendary durability: 30-50 years without degradation. There are porcelain tiles from the 1990s that are still perfect. It’s the material with the longest life expectancy in a residential bathroom.
- Zero material maintenance: No sealer needed, no reapplication of anything. Cleans with any product (including acids and bleach). The joints do need attention (cleaning, eventual re-grouting), but the ceramic piece itself is eternal.
- Virtually zero water absorption: < 0.5%. There’s no bathroom material more waterproof than porcelain tile.
- Immense aesthetic variety: Wood, marble, natural stone, concrete, metal, textile imitation. Digital inkjet printing has revolutionised the catalogue. At the CEVISAMA trade fair in Valencia, thousands of new designs are presented every year.
- Anti-slip options: Models with Class 3 (maximum) for shower floor, perfectly integrated aesthetically with wall pieces.
- Accessible pricing: Mid-range porcelain tile offers a value proposition that’s hard to beat.
Drawbacks
- Joints: Porcelain tile needs joints. Even rectified with 1.5 mm joints has visible lines. If you hate joints, porcelain tile will frustrate you (in that case, look at microcement or large-format slabs).
- Installation: Requires quality tile adhesive, notched trowel, diamond disc cutting and an experienced tiler. Not DIY for beginners.
- Weight: 20-25 kg/m² makes handling large pieces difficult. 320x160 cm slabs weigh 50+ kg per piece and need two people to install.
- Cold underfoot: Porcelain tile is cold to the touch. In winter, stepping barefoot on a porcelain floor at 7 AM is a rude awakening. Solution: electric underfloor heating (100% compatible with porcelain).
- Demolition to replace: If you don’t like it, changing porcelain tile means demolition, rubble and construction work. It’s not like removing a curtain.
Porcelain tile pricing (materials + labour, Valencia)
| Item | Price per m² |
|---|---|
| Budget porcelain (30x60, glazed) | €30-45 |
| Mid-range porcelain (60x60 or 60x120, rectified) | €45-70 |
| High-end porcelain (large format, premium marble/stone imitation) | €70-110 |
| Porcelain slab (120x260 or 160x320, 3-6 mm) | €90-150 |
| Installation (adhesive + labour) | €25-40/m² |
Total cost for a 5 m² floor + 12 m² walls bathroom (mid-range): €1,190-1,870.
SPC Vinyl: the disruptor you weren’t expecting
What it is
SPC vinyl (Stone Polymer Composite) is a composite cladding with a rigid core of limestone powder (60-70%) + PVC (25-30%) + plasticisers (5-10%), onto which a decorative layer is printed and a polyurethane wear layer is applied.
Don’t confuse SPC with conventional LVT (Luxury Vinyl Tile). LVT has a flexible core; SPC has a rigid core that doesn’t deform with humidity or temperature. This difference is fundamental for the bathroom.
For an in-depth analysis of SPC vinyl, check our dedicated article on SPC vinyl as a modern bathroom alternative.
Technical data
| Property | Value |
|---|---|
| Total thickness | 4-6 mm (without underlay) |
| Weight per m² | 7-10 kg |
| Compressive strength | 15-25 N/mm² |
| Water absorption (core) | 0% (100% waterproof) |
| Use classification | 23/33 (heavy residential / moderate commercial) |
| Wear layer | 0.3 mm (domestic) - 0.55 mm (commercial) |
| Wear resistance | Class T (maximum per EN 660-2) |
| Dimensional stability | Variation < 0.1% (EN 434) |
| Impact resistance | Good (doesn’t crack when objects fall) |
| Acoustic reduction | 6-15 dB (with acoustic underlay) |
| Anti-slip rating | R9-R10 (Class 1-2) |
| Phthalate content | Phthalate-free (in quality brands) |
Advantages
- 100% waterproof (the core): Water doesn’t penetrate SPC. Not through the click joints (if they’re sealed), not through the surface. For a bathroom, this means absolute peace of mind. Porcelain tile is waterproof, but its grout joints are not. SPC with sealed joints is waterproof across its entire surface.
- Floating installation (no adhesive): Installed with a click system over the existing floor. No glue, no mortar, nothing. Over old tiles: prepare, level if needed, and click. In a 5 m² bathroom, a professional installs it in 3-4 hours. Compared to the 2-3 days for porcelain, the difference is massive.
- Warm to the touch: Unlike porcelain, SPC doesn’t transmit cold. The sensation when stepping barefoot is temperate, even without underfloor heating.
- Lightweight: 7-10 kg/m² vs 20-25 kg/m² for porcelain. Less weight on the structure, easier to handle.
- Acoustics: Reduces impact noise by 6-15 dB. Porcelain is noisy (every step resonates). SPC dampens.
- Removable: If you tire of it, you lift the click floor and replace it without demolition. In a rental property, you can take your floor with you. It’s an advantage that no other material on this list offers.
Drawbacks
- Not suitable for shower walls with direct water impact: SPC is waterproof, but the click system has micro-joints that under direct water pressure (shower jet) can let moisture through behind the panel. For the bathroom floor and walls outside the direct shower zone, perfect. For the shower wall itself, better porcelain or microcement.
- Limited scratch resistance: The 0.3-0.55 mm wear layer can be scratched by sharp objects or dragged furniture. A shampoo bottle falling hard can leave a mark. It’s not a disaster (the mark is usually superficial) but it happens.
- Aesthetics: Has improved enormously, but a trained eye can distinguish SPC wood imitation from real wood or a high-end porcelain wood imitation. The depth of relief and tonal variation are inferior.
- Lifespan: 15-20 years in intensive residential use (bathroom). Less than porcelain (30-50 years) but more than microcement if you count the resealing cycles.
- Sensitivity to extreme heat: If water above 60 °C falls directly on SPC, it can deform locally. With a shower at 38-42 °C there’s no problem, but if a hot water tap splashes at maximum temperature, be careful.
- Perception as a “second-tier” material: In Spain, the perception persists that vinyl is a cheap, low-quality material. It must be acknowledged. A client investing €8,000 in a renovation may feel that vinyl on the floor “lets down” the ensemble. It’s a subjective but real perception.
SPC vinyl pricing (materials + labour, Valencia)
| Item | Price per m² |
|---|---|
| Budget SPC (4 mm, 0.3 mm wear layer) | €20-30 |
| Mid-range SPC (5 mm, 0.5 mm wear layer, acoustic underlay) | €30-45 |
| High-end SPC (6 mm, 0.55 mm wear layer, sealed joint, IXPE underlay) | €40-60 |
| Floating installation (labour) | €10-18/m² |
Total cost for a 5 m² bathroom floor (floor only, walls in other material): €150-390.
If you use SPC for flooring + porcelain on shower walls + microcement on remaining walls, you get a premium combination at a reasonable cost. We’ll discuss these combined strategies below.

When to choose each one
Choose microcement when…
- You want a seamless aesthetic and you’re willing to maintain the sealer.
- The bathroom is a design space where image matters more than practicality.
- You have the budget for a quality applicator (not the cheapest).
- The building is modern with a stable structure (reinforced concrete). In old buildings with shifting floors, the cracking risk is high.
- You don’t mind using only neutral cleaning products.
Choose porcelain tile when…
- You want uncompromising durability. Install the porcelain and forget about it for 30 years.
- You have children, pets or intensive bathroom use.
- You want cleaning flexibility (bleach, acid, whatever).
- Your budget is varied (there’s porcelain from €15/m² to €150/m²).
- You don’t mind joints (or use rectified with minimal joint).
Choose SPC vinyl when…
- You want to renovate quickly without wet trades.
- You’re in a rental property or want a reversible solution.
- You value comfort when walking barefoot (temperate, acoustic).
- The budget is tight and you want to maximise result per euro.
- You only need to cover the floor (shower walls will be in another material).
Combined strategy: the best of each world
At Bathscape, we’re increasingly executing renovations with a combined material strategy:
- General bathroom floor: SPC vinyl (warm, quick, economical)
- Shower walls and floor: Large-format porcelain (absolute waterproofing, durability)
- Accent wall (behind sink, WC): Microcement (premium aesthetic, no direct water impact)
Cost of this combination for a 5 m² floor + 12 m² walls bathroom: €1,100-2,000. Visual result: magazine-worthy. Practicality: maximum. It’s the best of the three individual options taken separately.
You can configure this combination in our BathBuilder and see how the combined materials look. You can also use the comparison tool to pit two options against each other and see the real price difference.
What manufacturers don’t tell you
Microcement
Many manufacturers advertise “waterproof microcement”. It’s a euphemism. Microcement is waterproof with the sealer in good condition. Without sealer, it absorbs 15-25% water. And the sealer degrades with use, cleaning and UV light (though in a bathroom UV is minimal). When a manufacturer tells you their microcement needs no maintenance, they’re either lying or selling a product that isn’t real microcement.
Porcelain tile
The wood or marble imitation classifications in catalogues are photographed with professional studio lighting. In your bathroom, under the usual fluorescent light, the Calacatta marble imitation porcelain doesn’t look as close to the original as in the brochure. Always request a physical sample and view them in the real bathroom, with your real light.
Also, large-format porcelain (120x260 or larger) needs a perfectly flat substrate. If the old tiles have level differences of more than 2 mm, levelling is needed before installation. That adds €150-300 and a day of work. Check our guide to technical errors in renovations to avoid these surprises.
SPC Vinyl
The “100% waterproof” in the advertising refers to the core of the material. But if water seeps in from the sides (for example, flooding where water rises over the edges of the floor), it can get trapped beneath the floating floor and generate mould on the underside. The solution is to seal the perimeter with waterproofing silicone, something many installers don’t do.
The smart decision: measure before you choose
Before deciding on a material, you need to answer five questions:
- How long will you live in that home? If less than 5 years, SPC (removable). If 10+, porcelain.
- Who uses the bathroom? Children and intensive use → porcelain. Adult couple → microcement or SPC.
- Will you maintain the microcement sealer every 3-5 years? If the honest answer is “no” or “I’ll forget,” rule out microcement.
- How much budget do you have for cladding? Under €1,000 → SPC floor + porcelain walls. €1,000-2,000 → complete porcelain or combined. Over €2,000 → microcement or premium porcelain.
- What aesthetic are you after? Seamless continuity → microcement. Realistic stone/wood imitation → porcelain. Quick and quality renovation → SPC.

Frequently asked questions
Can you put microcement over existing porcelain tile?
Yes, it’s one of the most common applications. Microcement is applied directly over porcelain with a specific adhesion primer. No need to demolish. The result is a seamless surface over the existing ceramic, with only 2-3 mm of added thickness.
Is SPC vinyl toxic?
Current quality SPC is free of phthalates and formaldehyde. Look for certifications like FloorScore or Greenguard Gold, which guarantee VOC (Volatile Organic Compound) emissions below health limits. Certified SPC is as safe as any other building material.
Can I put underfloor heating under SPC vinyl?
Yes, but with limitations. Electric or hot water underfloor heating is compatible with SPC as long as the surface temperature doesn’t exceed 28 °C (most manufacturers’ recommendation). SPC acts as a partial insulator, so the radiant system needs 10-15% more power to reach the same surface temperature as with porcelain.
How much does microcement maintenance cost over 10 years?
The polyurethane sealer needs reapplication every 3-5 years. In a 17 m² bathroom (floor + walls), that means 2-3 applications over 10 years at €150-300 each. Total: €300-900 in maintenance over 10 years. Compare with €0 for porcelain and €0 for SPC over the same period.
Which material adds the most value in a sale?
Mid-to-high-end porcelain tile and well-executed microcement are the ones that add the most perceived value in a property valuation. SPC vinyl doesn’t detract value but doesn’t add it significantly either. According to property portal data, a bathroom with large-format porcelain or microcement is valued 5-8% higher than one with standard ceramic. More data in our article on bathroom renovation ROI.
Can you combine all three materials in the same bathroom?
Yes, and in fact it’s what we recommend. The combination of SPC on the floor + porcelain in the shower zone + microcement on the accent wall is one of the configurations with the best quality-price-aesthetic ratio we offer. The key is that the tones are coherent with each other. Request physical samples of all three materials and compare them together in the real space before deciding. Configure it yourself in our configurator to visualise the result.
