Specifying bathrooms in multi-unit developments
Consistency, buyer options and technical coordination when one decision is repeated across many homes.
Fix a base specification per house type
Define a base bathroom, en-suite and cloakroom pack for each house type. Repetition reduces errors, simplifies ordering and makes snagging faster.
Check the plumbing system early
Showering performance depends on the hot water system and pressure. Confirm whether homes have combi boilers, unvented cylinders or heat pumps before selecting valves and shower heads.
Structure buyer options carefully
Offer a small number of curated upgrades with a firm cut-off date tied to first-fix. Late options are the most common cause of plot delays.
Plan tiling set-out with the sanitaryware
Agree tile size, grout lines and niche positions alongside basin and WC heights. A consistent set-out drawing per room type pays back on every plot.
