Waterproof Microcement Bathroom Banstead, Surrey
A layered mineral surface microcement bathroom designed for seamless continuity and durability, wterproof with every layer.
Specified in a light neutral colour match to the Farrow & Ball paint library.
Project Overview
A full microcement wet room installation finished in a coarse natural, colour-matched to Joa’s White by Farrow & Ball.
This project was designed to deliver complete waterproof integrity while maintaining a calm, mineral-led aesthetic.
The brief called for seamless continuity across floor and walls, no visual breaks, no tile lines, no thresholds, just a unified architectural surface.
We implemented our full “belts and braces” waterproof system, where it’s important to know when to install microcement in a bathroom renovation, ensuring resiliency at every stage of the build-up.
From substrate preparation through membrane reinforcement to final seal, the specification prioritised durability, slip resistance, and long-term performance within a fully saturated environment.
The selected coarse natural finish introduces subtle movement and tonal variation, allowing the space to feel grounded and textured rather than flat. The colour match to Joa’s White keeps the palette restrained; warm, quiet, and architectural, allowing light to move gently across the surface.
The result is a fully waterproof wet room defined by structure, mineral texture, and seamless composition.
Surface Specification
This Banstead wet room was constructed using a fully reinforced microcement system designed for continuous water exposure.
Substrate Preparation
The existing base was stabilised and mechanically prepared to ensure structural certainty and correct adhesion. Movement risks were addressed before build-up commenced.
Waterproof Reinforcement
A continuous membrane was installed across floors and walls, including all junctions and drainage interfaces. Corners and penetrations were reinforced to eliminate weak points.
This “belts and braces” approach ensures redundancy within the system — not reliance on a single barrier.
Microcement Build-Up
The coarse natural finish was applied in controlled layers, each keyed and cured before progression.
The texture introduces subtle mineral movement while maintaining slip resistance suitable for wet-room use.
Colour Integration
The surface was colour-matched to Joanna White by Farrow & Ball, aligning the finish with the wider architectural palette.
Pigment is integrated within the material itself, ensuring tonal consistency through the depth of the surface.
Protective Seal
A specialist sealing system was applied to deliver a fully waterproof, stain-resistant and durable finish suited to long-term saturation.
Water Demands Structure.
Texture Demands Control.
In a fully saturated environment, surface selection is not aesthetic alone, it is architectural. Every layer within this Banstead wet room was considered for durability, reinforcement and continuity.
Microcement only performs at this level when the system beneath it is structured correctly. Movement addressed. Junctions reinforced. Membranes continuous. Finish layered with intent.
Seamless is not a look.
It is a specification.

Every bathroom we install is a premium, belts-and-braces system: waterproof with each layer, so it does not rely on the sealer, with floors reinforced with fibreglass mesh. Choose from 42 standard colours or have us colour match to designer paint libraries, with finishes from polished to matte. Bathrooms start from £5,500 + VAT, and a site survey always confirms the written quote. Explore our microcement bathroom service, microcement floors, the microcement investment guide and our Amersham showroom, or get in touch for an initial estimate.

Banstead microcement bathroom questions
Do you install microcement bathrooms and shower rooms in Banstead?
Yes. We install microcement bathrooms, shower rooms and wet rooms in Banstead and across Surrey and London. Banstead is a service area: our showroom is in Amersham, by appointment, and we survey your property before confirming the written quote.
Is microcement waterproof in a shower?
Our microcement system is waterproof with each layer, with reinforced junctions and fibreglass mesh where the specification calls for it, so it does not rely on the sealer. The sealer adds stain resistance, longevity and sheen.
How much is the investment for a microcement bathroom?
Bathrooms start from £5,500 + VAT. A site survey always confirms the written quote, and additional areas such as walls, floors and ceilings across the project offer better value.
Can microcement be applied over existing tiles?
In many cases yes, subject to a survey of the substrate. Our guide to applying microcement over tiles explains when it works and when the tiles should come off.
What colours and finishes are available?
There are 42 standard colours on our factory chart, or we can colour match to designer paint libraries. Finishes run from polished to matte and in between, so the result suits your home.
