Will I need building regs sign-off?

Yes — adding a new WC requires building regs notification. We'll handle the install paperwork; the council issues the completion certificate.

Usually yes in Tunstall terraces, with a 100mm soil branch. If the stack is too far we'll spec a slim macerator unit.

Mandatory — a ducted fan (humidistat or timer) to outside is required. Recirculation isn't acceptable on a new internal WC.

Always. After a free home visit in Tunstall we send a fully itemised, fixed-price quotation — no surprises on invoice day.

Cloakroom Fitting · Tunstall

Downstairs WCs and compact cloakrooms in tight footprints.

Under-stairs cloakrooms are the most space-efficient bathroom upgrade most Tunstall terraces can make — and the most commonly fitted badly.

We size up the void, check the soil-stack run, and design around the sloped ceiling so you don't crack your head on the underside of the third tread.
