Planning a shower bath but unsure whether to go P-shape or L-shape? This guide breaks down the key differences, pros, cons, and which suits your bathroom layout and style.

If you're planning a bathroom renovation and want the best of both worlds — a relaxing soak and a proper shower — a shower bath is the perfect solution. But with P-shape and L-shape options available, which one should you choose? This guide breaks down the key differences so you can make the right decision for your space.

What is a Shower Bath?

A shower bath is a standard-length bath (usually 1700mm) with one end that's wider or shaped to create a more spacious showering area. This means you get a full-size bath and a comfortable shower enclosure in the same footprint — ideal for family bathrooms where space is at a premium.

What is a P-Shape Shower Bath?

A P-shape shower bath has a curved, rounded end at the shower end — resembling the letter "P" when viewed from above. The curved section creates a generous showering area that feels more like a dedicated shower enclosure, while the straight end remains a standard bath width for comfortable bathing.

P-Shape Pros:

• Larger, more open showering area
• Curved screen looks sleek and contemporary
• Great for taller users who need more elbow room
• Pairs with a curved bath screen for a seamless finish

P-Shape Cons:

• Requires a curved bath screen (slightly more expensive)
• The curved end can make it harder to fit in very tight alcoves

What is an L-Shape Shower Bath?

An L-shape shower bath has a squared-off, angular wider end at the shower side. When viewed from above it resembles an "L". The straight lines give it a more modern, architectural look and it pairs with a flat bath screen or shower enclosure panel.

L-Shape Pros:

• Clean, angular lines suit contemporary bathroom designs
• Pairs with standard flat bath screens — more choice and often lower cost
• Easier to fit into square or rectangular alcoves
• Generous showering area with a defined, squared feel

L-Shape Cons:

• The squared end can feel slightly less spacious than a P-shape curve
• Less forgiving if your bathroom walls aren't perfectly square

Which Should You Choose?

The right choice depends on three things: your bathroom layout, your style preference, and your budget.

• Go P-shape if you want maximum showering space and a softer, more curved aesthetic. It's particularly popular in family bathrooms where multiple people use the shower daily.
• Go L-shape if you prefer a sharp, contemporary look and want more flexibility with your bath screen choice. It's also a great option if your bathroom has a very defined rectangular alcove.

Size Considerations

Most shower baths are 1700mm long, which fits the standard UK bath space. The wider shower end is typically 850mm at its widest point, tapering back to the standard 700mm bath width. Always check the exact dimensions before ordering — and don't forget to account for the bath screen or panel.

Don't Forget the Bath Screen

Whichever shape you choose, you'll need a bath screen or shower enclosure panel to keep water contained. P-shape baths require a curved screen, while L-shape baths work with flat panels. Make sure your screen height (typically 1400–1500mm) suits your shower head position.
