Bath and Shower in the Same Bathroom: Layout Ideas That Work

You want the best of both worlds: a quick shower for weekday mornings and a proper soak whenever you feel like it. And there’s one question that keeps nagging at you — will it actually fit? Having a bath and shower in the same bathroom is not some impossible luxury, but it does depend on one number that almost nobody mentions upfront: how many square metres you have. Let’s give you that number straight, no beating around the bush.

The short answer: under 5 m² forget it, between 5 and 7 m² it’s tight but doable, and from 7–8 m² upwards you can breathe. The rest of this article explains why — so nobody sells you a layout that looks fine on paper but is a nightmare to live with.

Bath and Shower in the Same Bathroom: The Realistic Minimum Size

First things first — the dimensions of each fixture. A standard bath is 1.70 x 0.70 m. A decent shower, the minimum we’d recommend, needs a 90 x 90 cm tray, though 80 x 80 cm can work at a pinch. And on top of that you still need the toilet and basin — they don’t disappear.

The issue isn’t just the floor area each fixture takes up. It’s the clearance you need around it: the space in front of the bath to step in, room to open the shower screen, space to sit on the toilet without elbowing the wall. Here’s the table we use when deciding whether everything is going to fit.

Bathroom size	Bath + shower?	What to expect
Under 5 m²	Not realistic	You’ll have to choose one or the other
5–6 m²	Tight, with compromises	Small shower, very snug layout
6–7 m²	Possible	Comfortable if the shape helps
7–9 m²	Generous	Both fixtures with proper clearance
Over 9 m²	Plenty of room	Even a freestanding bath is on the table

Pay attention to that middle column. “Tight” means it fits physically, but you’ll end up with a cramped shower and very little room to move. There’s a big difference between something fitting and something being liveable.

Shape Matters as Much as Size

Two bathrooms measuring 7 m² can give completely opposite results depending on their shape. A square bathroom distributes fixtures far more easily. A long, narrow galley-style bathroom causes headaches because the bath takes up an entire wall and leaves little depth for the shower.

If your bathroom is one of those elongated ones, it’s worth reading how fixtures work in a long narrow bathroom before you commit to fitting both pieces in. Sometimes the solution is to put the bath at the far end — on the short wall — and tuck the shower right next to it, sharing a plumbing wall. That saves on pipework and precious centimetres.

Ceiling height matters too. In a loft bathroom with a sloped ceiling, the bath can sit under the lowest part of the slope where you don’t need to stand upright, while the shower goes in the area where you have full headroom.

How to Layout a Bath and Shower So They Don’t Get in Each Other’s Way

The layout that works best in tighter spaces is a linear one: everything lined up against one wall, or along two walls in an L-shape. Bath and shower together in the wet zone, toilet and basin opposite. This concentrates the plumbing in one area and leaves the rest of the bathroom clear.

A few tricks we use when space is at a premium:

• A shorter bath. Models at 1.50 m or even 1.40 m exist. You lose a bit of legroom, but you gain half a metre for the shower.
• A walk-in shower with a flush floor. A wet-room-style shower with continuous flooring looks bigger and removes the step.
• Fixed glass panel instead of a hinged door. No swing space needed. Have a look at the types of shower screens and how to choose — this is where centimetres are won or lost.
• A narrow wall-hung basin. Frees up floor space and makes the room feel larger.

Our honest opinion, after years of bathroom renovations in Valencia: if you have exactly 6 m², before insisting on squeezing both fixtures in, ask yourself honestly how often you’ll actually use the bath. If the answer is “twice a year,” a large well-designed shower will give you a far better quality of life than a bath that ends up as a glorified storage shelf. We say this without any agenda — sometimes the right answer is to let go.

What About the Budget?

Adding both a bath and a shower means two wet zones, two waste outlets, more waterproofing and more tiling. That pushes the cost up compared to a single-fixture bathroom. As a rough guide, a full bathroom renovation in the Valencia region typically runs between €6,000 and €9,000 depending on the finishes you choose, and a dual wet zone usually adds between €800 and €1,500 in materials and labour.

To get a figure based on your actual dimensions and chosen finishes, spend two minutes with our renovation cost calculator. And if you want to see real finished results before you decide, browse our bathroom design gallery.

It’s also worth keeping water consumption in mind: a full bath uses between 150 and 200 litres of water, versus roughly 50 litres for a five-minute shower, according to figures from the IDAE (Spain’s national energy efficiency agency). Having both options is great, but your water bill will reward you for reaching for the shower most of the time. We break this down further in our article on bath vs shower water usage.

On the product side: established brands like Roca already make compact bath ranges designed precisely for bathrooms where you want to keep the bath without giving up the shower. You don’t need to spend a fortune for it to look good.

When It’s Simply Not Worth Pushing for Both

If after doing the sums your bathroom comes in at 5 m² or under, forcing both fixtures in usually ends badly. You end up with a shower you can barely turn around in, a bath shoved up against the toilet, and the feeling that everything has been shoehorned in with no breathing room. In those cases, the sensible thing is to choose — and that’s perfectly fine.

If you want help making that call, our guide on bath or shower: how to choose is one of the most-read pieces on the blog, precisely because this is a dilemma that most homeowners face at some point.

Frequently Asked Questions

How many square metres do I need for both a bath and a shower?

From 6 m² it’s viable with a well-thought-out layout. At 5 m² it’s a very tight squeeze, and below that we wouldn’t recommend it — either the shower or the bath will end up too cramped to be comfortable.

Is it much more expensive than having just one fixture?

Yes, somewhat. Two wet zones mean extra waste outlets, more waterproofing and more tiling. Budget for roughly €800–€1,500 more than a single-fixture renovation, depending on the quality of finishes.

Can I use a bath with an overhead shower fitting to save space?

That’s a valid option if you’re short on space — a bath with a screen and a shower attachment above it. It’s not the same as having an independent shower enclosure, but it handles day-to-day use well and saves a couple of square metres.

What is the minimum acceptable shower size?

80 x 80 cm is the bare minimum for an adult. 90 x 90 cm is genuinely comfortable. Below 80 cm the shower feels claustrophobic and water splashes out easily.

Does the shape of the bathroom make a big difference?

Quite a lot, yes. A square 6 m² bathroom is far more flexible than a rectangular one of the same area, because you can distribute the fixtures more easily. Before ruling it out, it’s worth sketching the layout to scale.

The Bottom Line: The Number You Need to Check

Don’t sit there wondering whether it’ll fit. Get a tape measure, measure your bathroom, and compare it with the table above. From 6–7 m² onwards, a bath and shower in the same bathroom can coexist happily; below that, you’ll need to pick one, and that is absolutely fine. The important thing is that you make the decision with real numbers in front of you, not wishful thinking.
