The floor needs to be sufficiently sound, stable and properly prepared for the chosen finish. Significant unevenness can affect tile alignment, shower tray installation, furniture and drainage, so levelling or subfloor repairs may be required before the finished surface goes down.
Older Glasgow properties can have timber floors that have moved over time or previous layers of flooring built up at different heights. The correct preparation depends on the floor construction and its condition once the old finishes are removed.
Doherty's Glasgow bathroom installation service considers floor preparation and subfloor replacement as potential parts of the project. The important point is to fix the base first rather than trying to hide movement or unevenness with adhesive and tiles.
