A well-fitted bath panel hides pipework, protects the underside of the tub, and gives the bathroom a polished, finished look — something that matters equally in a private home, a holiday rental, or a hotel suite in Greece. The video above shows the process end to end; the steps below expand on each stage so you can work methodically and avoid the common mistakes. Most DIYers can complete the job in under an hour with basic tools.
Why Bath Panels Matter More Than You Think
The space beneath a freestanding or built-in bath is one of the easiest areas for moisture, insects, and dust to accumulate — especially in the humid summers common across Greece. A properly sealed panel keeps that void clean and inaccessible, extending the life of pipework and flooring alike.
For rental properties and hotels, a missing or cracked bath panel is also an immediate visual cue of poor maintenance that guests notice. Replacing or refitting one is one of the highest-return cosmetic upgrades you can make before a new season.
Choosing the Right Panel Material
Acrylic panels are the most common choice: lightweight, water-resistant, and available in sizes that match almost any standard bath. MDF-backed or wooden panels suit period-style bathrooms but require a sealed edge to resist moisture — important in any bathroom that sees heavy use.
For holiday apartments that rotate guests frequently, an acrylic or PVC-core panel is the practical choice. It wipes clean, resists knocks better than timber, and does not warp if a shower is fitted over the bath.
How to Fit a Bath Panel in 5 Steps
- 1
Measure and trim the panel to size
Measure the length of the bath from wall to wall and the height from the floor to the underside of the bath rim. Most panels come slightly oversize; use a fine-tooth saw or a multi-tool to trim to the exact height. Allow a 5 mm clearance at the floor to prevent the panel wicking up moisture from wet tiles.
- 2
Mark the support batten positions
Hold the panel against the bath and mark where the top and bottom support battens need to sit. The top batten typically clips to the bath's own framework or sits just below the lip; the bottom batten rests on or near the floor. Use a spirit level to keep both horizontal before fastening.
- 3
Fix the battens to the wall or bath frame
Screw the top batten to the underside of the bath flange or to the wall studs with stainless steel screws. In tiled bathrooms, use a suitable masonry anchor. Fit the bottom batten to the floor with screws or strong adhesive pads. Check that both battens are level and parallel — this is what determines whether the finished panel sits straight.
- 4
Clip or slide the panel into position
Most modern acrylic panels locate on the battens with a push-fit or clip system. Slide the top edge up behind the bath rim and then press the lower edge onto the bottom batten. On panels that use a screw-fix system, pre-drill pilot holes to prevent cracking, then fasten with the provided screws and cover caps.
- 5
Seal the edges with sanitary silicone
Apply a bead of white or clear sanitary-grade silicone along the joint where the panel meets the wall and along the floor edge. Smooth with a wet fingertip or a caulk tool and leave to cure for at least 24 hours before using the bath. This seal is critical in Greece's warm, humid climate to prevent water ingress behind the panel.

FAQ
- Do I need to remove the old panel before fitting a new one?
- Yes. Remove the old panel completely, scrape away any old silicone, and check that the battens or support clips are still solid. Fitting over an existing panel creates uneven gaps and makes it harder to get a watertight silicone seal.
- What if my bath panel is slightly too short for the gap?
- A small gap at the floor (up to about 10 mm) can be filled with a generous silicone bead and a matching bath sealant strip. A larger gap usually means the panel is the wrong size for your bath — check the bath manufacturer's recommended panel height before purchasing.
- Can I make the panel removable for plumbing access?
- Yes, and it is worth doing. Instead of silicone at the panel edges, use magnetic catches or hook-and-loop fastener tape on the battens. The panel clips in firmly, looks neat, and can be lifted off in seconds if a plumber needs to reach the pipework — a practical feature for rental properties.
