Project brief

Renovating a bathroom: prepare the project before work begins

A successful renovation starts with the invisible constraints: finished levels, water supply, drainage, ventilation and technical access. Product choices follow once the layout is clear.

Method

Key checks before a bathroom renovation: services, layout, shower, WC, basin, materials and maintenance access.

01

Survey the existing space precisely

Before moving a shower, WC or basin, record the services and constraints of the room. A measurement taken from a bare wall can change after waterproofing, adhesive and finishes.

  • Measure from planned finished levels
  • Confirm drainage position and diameter
  • Check supports, ventilation and service access
02

Coordinate what must work together

Shower, WC, basin, furniture and taps form one system. Useful dimensions, spray zone, falls and operating clearances matter as much as the finish.

  • Allow the depth required for concealed parts
  • Validate the basin–mixer combination from dimensioned sheets
  • Plan waterproofing and waste before tiling layout
03

Prepare validations before ordering

A simple file prevents late site decisions. Drawings, selected references, useful dimensions and photos of the existing space allow compatibility to be checked before installation.

  • Keep references for concealed and visible components
  • Confirm quantities, shades and formats with the layout
  • Plan an intermediate inspection before closing walls

Frequently asked questions

Clarify these points before starting.

01When should taps be selected?

After the layout, basin, finished heights and concealed-installation requirements have been confirmed.

02Can a drainage point be moved?

It depends on the existing network, available falls and required works. Check it before finalising the layout.

03What should be prepared for an appointment?

A plan, photos of the existing space, useful dimensions and any shortlisted references make a first selection more effective.
