How do I design a combined shower tub for flexible bathing?

Right, so you’re thinking about a shower tub combo. Blimey, takes me back to my first flat in Clapham—tiny bathroom, one sad-looking tub from the 80s, and me thinking I could just whack a shower above it and call it a day. Let me tell you, that was a proper disaster waiting to happen. Water everywhere, the shower curtain clinging to you like a ghost… not what you’d call flexible bathing, more like a daily obstacle course.

Honestly, flexibility starts long before you pick a tap. It’s about how you live. Take my mate Sarah—she’s in Canterbury, converted an old bakery into a home. She swore she wanted a deep, standalone tub for weekend soaks. Lovely idea, till she realised her bad knee made climbing in and out a nightmare. She ended up with a low-threshold tub from Victoria Plum, something with a wide rim you can actually sit on. Added a handheld shower on a slider rail—game changer. Now she can soak when she wants, shower when she needs, without feeling like she’s mountaineering.

And size? Don’t just eyeball it. I learned that the hard way in a project in Bristol—gorgeous Victorian terrace, bathroom the size of a postage stamp. We squeezed in a 1500mm tub-shower, but forgot about the door swing. Ended up with a bi-fold screen instead of a curtain. Sounds small, but that little pivot made all the difference. You could actually move without elbowing the sink.

Materials matter more than you’d think. That glossy acrylic tub might look smart in the showroom, but get a cheap one and it feels… wobbly. Like stepping onto a biscuit tin. I once fitted a steel tub from B&Q—looked sturdy, but the noise when the shower hit it? Sounded like hail on a conservatory roof. Switched to a cast iron one later—heavier, yes, but solid as a rock and kept the heat for ages. Felt like a proper soak, not a race against time.

Oh, and the tapware—don’t skimp here. I fitted a thermostatic mixer in my own place last spring, thinking it was a luxury. Turns out it’s a sanity-saver. No more jumping out because someone flushed the loo and turned you into a lobster. And get a diverter valve that actually clicks into place. The number of times I’ve had clients moan about tepid water dribbling from both the shower and the tap… usually because they went for the cheapest valve from a dodgy online seller.

Lighting! Almost forgot. If you’re using it as a shower, you’ll want something bright and even—none of that single, grim bulb over the mirror. But for a bath? Dimmer switch, maybe even a waterproof LED strip along the skirting. I put one in for a bloke in Manchester who liked to read in the tub. Changed the whole vibe from “clinical” to “spa evening,” even if his spa was overlooking a Sainsbury’s car park.

And storage—crikey, yes. Where does the shampoo go? The loofah? I fitted a little recessed niche in the tiling for a client in Leeds. Just two shelves, but it meant no clunky caddies hanging off the tap. Felt seamless. Looked smart.

At the end of the day, it’s not about having both options—it’s about making them work for you, every day. Whether it’s a quick rinse after a jog or a long soak with a cuppa, the thing shouldn’t feel like a compromise. My grandma used to say a good bathroom feels like a hug at the end of the day. Cheesy, maybe. But when you get it right—the warmth underfoot, the sound of the water, the ease of it all—you’ll know exactly what she meant.
