Bathroom renovations in East London
Blackstone takes on bathroom renovations as well as individual bathroom plumbing jobs. A useful renovation plan brings the layout, water supply, waste routes, fixture choices and waterproofing responsibilities together before finishes are ordered.

Define the bathroom you are changing
List what is staying, what is being replaced and what is moving. Replacing a basin in its existing position is a different project from relocating a toilet or creating a walk-in shower. Note who uses the room, storage needs and whether another usable bathroom is available during work.
Check plumbing before agreeing the layout
Existing waste positions, drainage falls, ventilation, pipe condition and hot-water supply may limit an attractive design. Moving a toilet can require more invasive drainage work than moving a tap. Confirm the feasibility of proposed positions before ordering fixtures, especially in upper-storey rooms or where the floor structure limits access.
Fixtures, drainage and waterproofing
Select fixtures with compatible supply and waste connections. A shower floor needs suitable drainage and a properly planned waterproofing system; tiles and grout alone are not waterproofing. Agree who is responsible for substrate preparation, waterproofing, inspection and finishing, including around pipe penetrations. Do not assume every building trade is automatically included.
Typical project stages
The sequence is scoped to the property rather than a guaranteed schedule.
- Site assessment and agreed layout, inclusions and exclusions.
- Safe isolation, removal and investigation of existing plumbing.
- Supply and waste alterations before closing walls or floors.
- Coordinated waterproofing and finishes with the responsible trades.
- Fixture installation, leak checks, drainage checks and handover.
What changes the cost
Room size, moved waste points, concealed faults, fixture quality, wall and floor access, waterproofing scope and making good all influence the quote. Luxury fittings do not compensate for an unsuitable waste route. Request an assessment rather than relying on a generic square-metre price.
Mistakes to avoid before work starts
Do not order a bath that cannot pass through the access route, close walls before plumbing checks or leave responsibility for waterproofing undefined. Keep the agreed scope in writing and discuss discoveries in old pipework before additional work proceeds.
Frequently asked questions
Can Blackstone help with a complete bathroom renovation?
Yes. Request a site assessment to define the project. Confirm the plumbing, fixtures, waterproofing coordination, finishes and any other trades included in your quote.
Should I move the toilet to improve the layout?
Only after the existing drain route and access have been assessed. A new position can substantially change the plumbing work and cost.
