Choosing the right bath panel size shouldn’t be confusing — but for most homeowners, it is. Bath panels come in a mix of standard and non‑standard sizes, bath heights vary, and older bathrooms often don’t match modern dimensions.
This guide explains every bath panel size, how to measure correctly, and what to do when your bath isn’t a standard size. Whether you’re replacing an old panel or fitting a new bathroom, this is the definitive UK sizing guide.
Quick Size Summary
- Standard front panel lengths: 1500mm, 1600mm, 1700mm, 1800mm
- Standard end panel widths: 700mm, 750mm, 800mm
- Standard height: 480–520mm (adjustable with plinths)
- L‑shaped & P‑shaped panels: manufacturer‑specific
- Non‑standard baths: choose Cut‑to‑Size Bath Panels
- Always measure the bath itself, not the old panel
1. Standard Bath Panel Sizes (UK)
Most UK straight baths follow a small set of standard lengths and widths. These are the sizes you’ll see across most retailers and manufacturers.
Standard Front Panel Lengths
- 1500mm
- 1600mm
- 1700mm (most common)
- 1800mm
Browse: Standard Bath Panels
Standard End Panel Widths
- 700mm
- 750mm
- 800mm
Browse: End Bath Panels
Standard Bath Panel Height
480–520mm
This varies because bath legs are adjustable and many panels include a plinth to fine‑tune the height.
If your bath height is unusual, choose a panel with a plinth or go custom.
2. How to Measure Your Bath Correctly
Most fitting issues happen because people measure the old panel, not the bath. Here’s the correct method.
A. Measuring the Front Panel
Measure:
- Length — wall to outer bath edge
- Height — floor to underside of bath rim
If the floor is uneven, measure both ends and use the tallest point.
B. Measuring the End Panel
Measure:
- Width — wall to outer bath edge
- Height — same method as above
C. If your bath is tiled in
Measure the visible opening, not the bath shell.
D. If your bath is boxed in
You may need to remove the old panel to measure accurately.
3. When Your Bath Isn’t a Standard Size
This is extremely common — especially in older homes or bathrooms that have been retiled.
Typical non‑standard scenarios:
- Bath length is 1650mm, 1720mm, 1685mm, etc.
- Bath height is too tall for standard panels
- Bath sits in a tight alcove
- Floor is uneven
- You need to work around pipework or boxing

4. Bath Panel Heights Explained
Height causes more confusion than length.
Why height varies:
- Adjustable bath legs
- Uneven floors
- New flooring added after installation
- Deeper bath shells
Typical height ranges:
- 480mm — low baths
- 500mm — standard
- 520mm+ — deeper or raised baths
If your bath height exceeds 520mm, choose:
- A taller panel, or
- A cut‑to‑size panel
5. L‑Shaped & P‑Shaped Bath Panel Sizes
These panels are not universal — they must match the exact bath model.
L‑Shaped Panels

- 1700mm front
