Strip out a bathroom (prep for renovation)
Save £150–400 in half a day — no contractor needed
Most people pay a tradesperson to do this. The strip-out is entirely DIY-able — and doing it yourself means you know exactly what condition everything is in before the new work starts.

Only basic tools needed — most homes already have them.
Before you start
This is Phase 1 of a full bathroom renovation. Do this before any new fixtures, tiling, or plumbing work.
Turn the water off and confirm it is isolated before removing anything connected to the supply.
Have a plan for what is being replaced and what is staying — it saves unnecessary removal work.

Turn off the water supply
Locate the isolation valves under the basin and behind the toilet cistern. Turn each valve 90 degrees until it sits across the pipe. Turn on the taps to release any remaining pressure and confirm the water is off. If there are no isolation valves, turn off the main stop cock.
Most people get this done in under 5 minutes.
Quick guides for this phase
How to remove old silicone sealant without damaging tiles →Where beginners go wrong
Not fully isolating the water before disconnecting pipes — a small amount of water is always left in the pipes after isolation, so have a bucket ready.
Removing fixtures that were planned to stay — decide exactly what is being replaced before you start and mark it clearly.
Skipping tile removal and tiling over old tiles — this builds up thickness and can cause grout cracking. Only keep old tiles if they are fully bonded and flat.
Not checking for damp before covering walls — hidden damp behind old tiles or fixtures is the most common cause of future problems. Look, smell, and press on plaster to check.
Stop and call a plumber if...
The main stop cock will not fully close — do not proceed with any disconnection until water is fully isolated
You find significant damp, black mould, or soft/crumbling plaster behind fixtures — this needs professional assessment before new work starts
The waste pipe from the toilet is cracked or damaged — this is a job for a qualified plumber

⚠️ Watch out if you rent
Never strip out a bathroom in a rented property without written permission from your landlord. Removing fixtures or tiles is a major change. Get everything agreed in writing before you start.
