Waterproof, ventilated and practical

Bathroom renovation in London

Renovate your bathroom with the waterproofing, drainage, ventilation, tiling and fittings considered as one coordinated installation.

A practical overview

Planning bathroom renovation properly

Bathrooms place demanding finishes over concealed plumbing and electrical work. Careful preparation matters because leaks, poor falls or inadequate ventilation can cause damage long after the visible work looks complete.

COFAD can coordinate complete bathroom renovation or an agreed partial upgrade. We review the proposed layout, product specifications, existing services and room condition before defining the work and installation sequence.

Transparent scoping

What affects the work and quotation

  • 01Room size and condition behind existing finishes
  • 02Layout changes and drainage routes
  • 03Tile size, pattern, substrate and area of coverage
  • 04Sanitaryware, brassware, screens and furniture specification
  • 05Ventilation, lighting and underfloor heating requirements
  • 06Access, waste removal and protection of the property

Choose sanitaryware and brassware before first fix wherever possible. Technical dimensions determine pipe positions, concealed frames, niches, screen clearances and the finished layout.

For flats and older properties, drainage position, water pressure, floor construction and ventilation routes can limit the layout. An early site review helps distinguish preferences from practical constraints.

Common questions about bathroom renovation

Can you renovate a small London bathroom?

Yes. Compact bathrooms benefit from careful product sizing, door and screen clearances, storage planning and realistic drainage routes.

Can a bath be replaced with a walk-in shower?

Often yes. We first check the available footprint, drain position, floor construction, waterproofing area and screen arrangement.

Do you install underfloor heating?

Electric underfloor heating can be included where suitable. The floor build-up, controls, electrical requirements and chosen floor finish must be coordinated.

Who supplies tiles and sanitaryware?

Either arrangement can be discussed. Responsibility for selection, quantities, delivery and damaged items should be written into the scope before work starts.

Can you add an en-suite?

Potentially, if there is enough space and workable routes for water, drainage, ventilation and power. Layout and approval requirements should be reviewed first.
