Bathroom renovation is one of Hong Kong's most common partial renovation projects, especially for units over 15 years old. Barrier-free bathroom design demand is rising with an aging population. Fixture brands offer free planning services, but designs are limited to their product lines.
Waterproofing is the top priority. Ensure the design specifies waterproof membrane height (floor-to-ceiling in shower areas) and materials. Anti-slip floor tiles and adequate drainage slope are non-negotiable safety requirements.

Frequently Asked Questions
Not necessarily. If waterproofing is intact and drainage is functional, partial renovation (new fixtures, re-tiling) is possible. However, if water seepage or tile delamination exists, full demolition with new waterproofing is the safer long-term approach.
In 20–30 sqft bathrooms, a half-height glass screen or folding shower screen provides basic separation without taking up excessive space. Floor level differences with linear drains are another space-efficient approach.
