If you’re unsure how to fit a bath panel, don’t worry - use our guide on how to fit a bath panel and you’ll be luxuriating in a bubble bath in no time at all!
Alternatively, find a local bathroom fitter and that relaxing bath will be even closer than you think.
Step By Step Instruction For Fitting A Bath Panel
If you’re replacing an old bath panel, unscrew it from the bath frame and you should be able to pull it out easily.
There are a few awkward bath panels that will have hidden fittings or brackets, so make sure that you unscrew these too.
Once you’ve removed the old bath panel, you’re ready to measure up for the new one.
If you’re lucky, your bath panel will already fit your bath but in many cases, you’ll have to tailor the bath panel to your requirements.
Building A Bath Panel Frame
Before you do this, you should build a wooden frame for the bath panel.
This will secure it in place and reinforce the bath panel against bumps and knocks in the future.
Make sure the timber you use is strong enough to stabilise the bath panel - 50 x 25mm timber is ideal.
If a wooden frame is not an option, then try to fix some timber along the floor at the bottom of the bath - that way, you’ll stop any movement to the bottom of the bath panel.
Remember, if DIY’s not your thing, get some competitive prices from your local bathroom fitters.
It’ll be worth it in the long run and you’ll avoid any damage to your bathroom units or yourself!
Before you start to cut, make sure that cutting your bath panel will not damage its construction.
Now measure the void underneath the bath and cut your bath panel to fit this space.
A handy tip to keep in mind is to measure twice, cut once.
Tools Needed
A fine blade jigsaw or handsaw should be perfect for cutting your bath panel, and can tackle either acrylic or wood.
Be careful not to damage your new bath panel by using excessive force!
If you’ve cut a wooden bath panel to size, be sure to add some PVA glue to the end where you cut, it will stop any water from seeping through.
Now you’re ready to secure the bath panel.
Place it under the lip of the bath, then screw the panel onto the frame.
Then it’s just a case of screwing the panels together.
Mirror screws will give it a professional looking finish - just the touch to complete the perfect look for your bathroom.
Frequently Asked Questions About Fitting a Bath Panel
1. What is a bath panel and why do I need one?
A bath panel is a cover that conceals the underside and plumbing of your bathtub. It serves both aesthetic and practical purposes:
-
Hides unsightly pipework and framework
-
Prevents water and debris from getting underneath
-
Enhances the overall finish of the bathroom
Most panels are installed on the front (long side) and sometimes the end (short side) of the bath.
2. What materials are bath panels made from?
Bath panels are typically made from:
-
MDF (moisture-resistant fibreboard) – Common and budget-friendly, usually coated with a white or wood-effect vinyl.
-
Acrylic (plastic) – Lightweight and waterproof; flexible and ideal for curved or P-shaped baths.
-
Solid wood or veneer – Premium option for traditional or luxury bathrooms.
Each material has different fitting methods and durability levels.
3. Do all bath panels fit all baths?
No. Panels vary in length, height, and curvature. To ensure the correct fit:
-
Measure the length and height of your bath area.
-
Check if your bath is straight, L-shaped, or P-shaped.
-
Buy a panel that is compatible with your bath type—some are universal and can be trimmed, others are shape-specific.
4. How do I measure for a new bath panel?
To get accurate measurements:
-
Measure the length from wall to wall along the front of the bath.
-
Measure the height from the floor to the underside of the bath lip.
-
For L- or P-shaped baths, also trace the curve or angle to match with a shaped panel.
Some panels come oversized with a trim-to-fit feature, especially MDF types.
5. What tools do I need to fit a bath panel?
Typical tools include:
-
Tape measure
-
Pencil
-
Handsaw or jigsaw (if trimming is needed)
-
Screwdriver or drill
-
Spirit level
-
Silicone sealant and caulking gun
-
Wooden battens (for support, if not supplied)
Optional: Clamps, panel clips or magnetic fasteners if you're creating a removable panel.
6. Do I need a frame or support behind the panel?
Yes, in most cases.
If the bath panel doesn’t come with a built-in support system:
-
Fix timber battens (usually 25x50mm) to the floor and walls to help hold the panel in place.
-
These act as a ledge or track for the panel to sit against and prevent movement.
Some plastic panels have built-in clips or adjustable feet.
7. How do I trim a bath panel to size?
Use a fine-tooth handsaw or jigsaw for cutting MDF or wooden panels. Score the cutting line clearly and support the panel while cutting to avoid splintering.
For plastic panels:
-
Use a fine blade and cut slowly to avoid cracking.
-
Sand any rough edges for a clean finish.
✂️ Tip: Always measure twice and cut once!
8. How do I fix a bath panel in place?
There are a few common fixing methods:
-
Screw it to battens fixed along the floor or walls.
-
Use panel clips for a neater, removable solution (ideal for access to pipework).
-
Magnetic fixings allow for easy removal and reattachment.
Seal the top and sides with silicone sealant once the panel is fixed to ensure water resistance.
9. Can I make the bath panel removable for access?
Yes, and it’s often a smart idea—especially if you ever need to access plumbing.
-
Use magnetic fixings or spring clips instead of screws.
-
You can also build a frame with Velcro or hook-and-loop pads for easy access.
-
Avoid sealing the entire panel permanently unless access isn’t a concern.
10. Should I seal the edges with silicone?
Yes—once the panel is installed and level:
-
Run a bead of bathroom-grade silicone along the top edge where it meets the bath.
-
Also seal vertical edges where they meet the wall or floor.
-
This prevents water from seeping under the panel and causing damage or mould.
Allow the sealant to fully cure (usually 24 hours) before using the bath.
✅ Final Thoughts
Fitting a bath panel is a straightforward DIY task, but it makes a big impact on the look and longevity of your bathroom. Taking the time to measure carefully, choose the right panel, and install it securely will ensure your bath looks smart and stays protected from moisture.
