the wet-room. one continuous mineral skin.

why full-plaster
A tiled bathroom is a grid of grout lines. A vinyl-plank bathroom floor is a grid of click-lock seams — sitting directly in the splash zone around the floor trap. A microcement bathroom is one continuous sealed mineral surface from skirting to ceiling, no joint anywhere in the wet zone. For wet areas we only specify authentic microcement plaster, on walls and on floors.

what we do not recommend
We do not install SPC vinyl planks in toilets or any wet area. SPC plank faces are waterproof, but the click-lock seams between planks are not a continuous waterproof skin — and in a bathroom those seams sit directly in the splash zone. Over time, water finds the joints, the underlay, and the substrate. SPC remains our preferred floor for dry areas (living, dining, bedrooms, hallways); for wet areas, plaster.
faq
is microcement waterproof in a singapore bathroom?
Yes, once sealed. The 2–3mm plaster is laid in layers on walls and floor, then finished with a dedicated waterproof topcoat sealer — that is the system that lets it work directly behind a shower head and underfoot in the splash zone.
why not spc vinyl in the toilet?
We do not recommend SPC vinyl planks for wet areas. Plank seams sit in the splash zone around the floor trap and shower; over time water finds the click-lock joints and the underlay. Microcement plaster is one continuous sealed skin — no seams, no joints, no entry points.
how long is the bathroom out of use?
Plan for ~9 days end-to-end: walls (multi-layer plaster + sealer cure), floor (separate plaster + sealer cure), and reinstatement.
do i need to hack the existing tiles?
Sometimes not. If the tiles are flat, sound, and bonded, microcement plaster bonds directly over them with a primer — on walls and on the floor. We confirm at the site check.
