About Us
Equally at home in large minimalist spaces and tight ones, where material and detailing build visual volume.
A London-based installation studio specialising in high-end bathrooms.
Our Mission
A high-end bathroom is defined by how well it is executed on site — not just by the materials used. We carry the design intent through every stage: setting-out, substrate, detailing and finish.
The Studio
FacetStudio is led by Mihail Cheptene, fifteen years in the trades, the last five in London.
He came to bathrooms sideways — through plumbing, carpentry and electrical work, shaped by practice more than paper. The specialisation began at second fix. Returning to finished rooms to hang the sanitaryware, he kept finding how far the built result had drifted from the drawing: never through one large mistake, but through a hundred small decisions taken on site by people who had never looked at the design.
Everything the studio does now follows from that. Setting-out before the first tile is cut. The substrate treated as the thing that decides the finish, not the thing hidden by it. And the same pair of hands from first fix to handover, so nothing is lost in the gaps between trades.
Projects run one to two months and are taken on one at a time. Where a programme calls for a larger team, we bring in people we have worked with before. FacetStudio is a trading name of Electroplumbs Service Ltd — the plumbing and electrical work is carried in-house, not subcontracted.

How We Work
A process built around one principle: the finished bathroom should match the drawing — not approximate it.
01
Survey & Setting-Out
We review the design drawings, survey the space and set out tile geometry, fittings and levels before any work begins — so decisions are made on paper, not improvised on site.
02
Substrate & First Fix
Squaring up, screeding, tanking and first fix plumbing — the invisible work that determines whether the visible work can be flawless. Flat, square, waterproof, level.
03
Tiling & Detailing
Large-format porcelain, mitred edges, aligned joints and consistent grout lines. Every cut and transition is executed to hold the visual flow of the space, not just to cover the wall.
04
Second Fix & Handover
Sanitaryware, brassware and final detailing installed and sealed. The space is handed over finished — matching the design intent it started from.
Selected Work
High-end bathrooms across London — large-format porcelain, mitred detailing and wet rooms built to the drawing.
