A double shower with two shower heads sounds like something from a five-star hotel — and honestly, it is. Two independent jets, two people at the same time without fighting over the hot water, each at their own temperature. When it works, it’s one of those upgrades you’ll be grateful for every single morning. When it’s shoehorned into a bathroom that isn’t big enough, it’s money down the drain and a screen that always leaks somewhere.
So let’s get straight to it: when it actually makes sense, what you need to do it properly, and where the pitfalls are.
What Is a Double Shower with Two Shower Heads (and Why It’s Not for Everyone)
We’re talking about a large shower tray with two separate water points: two fixed shower heads mounted on the ceiling or wall, each with its own valve and — ideally — its own thermostatic control. This is not the same as fitting one enormous rain head and opening two taps from the same thermostat. That’s a big shower, not a double one.
The key difference is independence. If you want the water at 38°C and your partner wants it at 42°C, two separate thermostatic circuits give you exactly that. With a single circuit, someone always loses. That independence is the whole point — and it’s also what makes the installation more expensive.
And here’s our honest take: we don’t recommend it for everyone. It’s brilliant in the master bathroom of a couple sharing busy mornings. In a small bathroom, or in a home where only one person uses the shower, you’re spending significantly more for something you’ll barely use.
Space: The First Question — Before You Even Think About Money
Before you start looking at shower fittings or tiles, get a tape measure out. For two people to use it comfortably without constantly elbowing each other, you need a generously sized shower tray.
| Configuration | Minimum recommended dimensions | Real comfort level |
|---|---|---|
| Compact double | 120 × 90 cm | Tight — works best with opposing heads |
| Comfortable double | 160 × 90 cm | Our standard recommendation |
| Spa-style double | 180 × 100 cm or more | Ideal, but requires a large bathroom |
Below 120 cm wide, forget it. Two people in just over a metre is claustrophobic, not luxurious. In our experience, 160 cm is the sweet spot — one head at each end, with a dry zone in the middle where you can soap up in peace.
If your master bathroom doesn’t quite reach those dimensions, don’t rule it out straight away. Check whether you can gain space by removing the bathtub. We cover this in our article on the signs it’s time to swap your bath for a shower — very often, the metre and a half you need is being taken up by a bath that nobody actually uses.
The Plumbing: Where Things Get Complicated
The shower heads themselves are the easy part. What costs time and money is what you can’t see.
Two shower heads with independent temperature control means two thermostatic valves and, crucially, enough flow rate and water pressure to feed both simultaneously. If your pipework is already running at its limits, open both jets and they’ll both run weak. A decent-sized ceiling rain head can demand 15–20 litres per minute; two running at the same time means 30–40 litres. Not every domestic installation can deliver that without reinforcement.
This is why a double shower renovation almost always involves inspecting — and sometimes replacing — the supply pipework. If your flat is more than a few decades old and the plumbing has never been touched, now is the moment to look at it; we explain when it’s worth replacing your bathroom pipework in more detail. Doing it afterwards, once the tiles are already on the wall, means breaking everything open again.
One more thing: hot water supply. Two showers running simultaneously will drain your water heater fast, and a small electric tank will run cold within minutes. If you plan to use the double shower simultaneously on a regular basis, you’ll want to consider a boiler or a larger-capacity hot water cylinder. There’s nothing more dispiriting than a double shower that goes cold five minutes in.
The Drain and the Fall
More water coming in means more water that has to get out. A single central drain can struggle with two jets running at full blast. On large shower trays, the standard solution is a well-sized linear drain (channel drain) or two separate outlet points. The fall of the tray needs to be calculated across the entire surface, not just one corner. It’s a technical detail that makes the difference between a shower that drains cleanly and one that permanently pools.
What It Costs — No Gloss
The extra cost of a double shower over a standard shower doesn’t lie in the two heads themselves — it’s in the larger tray, the second thermostatic valve, the reinforced plumbing and the bespoke screen. Here’s a price guide for the additional cost, based on the Valencia region in 2026:
| Item | Approximate cost |
|---|---|
| Large shower tray (160 cm or wider) | €350 – €900 |
| Second thermostatic set + shower head | €400 – €1,200 |
| Plumbing reinforcement / new pipework | €300 – €800 |
| Bespoke shower screen (wider format) | €600 – €1,500 |
| Linear drain | €150 – €400 |
All in, the upgrade from a standard shower to a well-executed double typically adds between €1,500 and €3,500 on top of the cost of a regular shower renovation, depending on quality and the current state of your installation.

It’s worth keeping things in perspective: bathrooms are among the most expensive rooms per square metre in any home. Two people showering simultaneously will use more water per session, though you’ll also spend less total time with the bathroom occupied. A double shower is not designed to save water — it’s designed to save you time and reduce stress in the mornings.
When a Double Shower IS Worth It
To summarise — because that’s the whole point of this article:
- You’re a couple sharing busy mornings. This is where a double shower pays for itself in quality of life. No more queueing.
- You have a spacious master bathroom (160 cm or more for the shower) and you’re already planning a full renovation. If you’re opening up floors and walls anyway, the relative extra cost is lower.
- You want a spa-style bathroom and the shower is the centrepiece. Two opposing rain heads are a genuinely striking design statement.
- You’re planning to stay in the property for years. This is a lifestyle upgrade, not a quick-sale feature. You won’t recoup it on the resale market; you’ll enjoy it every day you live there.
And when it’s not worth it: small bathroom, single occupant, tight budget, or pipework you don’t want to disturb. In those cases, a good single shower with one large rain head gives you 80% of the experience at a fraction of the cost.
Mistakes We See All the Time
The most common one: fitting two heads but sharing a single thermostat to save money. You lose the best thing about a double shower — independent temperature control. If you’re going to cut costs, cut them somewhere else.
The second: underestimating the shower screen. A double shower needs a wide, well-fitted enclosure, otherwise half your bathroom ends up wet. This is where choosing the right shower screen glass thickness matters — a wide screen in thin glass will flex, rattle and age badly.
The third, and the most expensive to fix: skipping the plumbing reinforcement, then discovering that both jets run at low pressure once everything is already tiled. This is precisely why we harp on about checking your pipework and pressure before work begins. It’s one of those classic bathroom renovation mistakes that only becomes visible when it’s too late to fix cheaply.
A quick note on brands: if you want rain heads with a genuinely good flow rate, manufacturers such as Roca and Grohe both have ranges designed specifically for this use case, with published flow and pressure specifications on the data sheets. Get those specs before the installation is finalised so the plumber can size everything correctly.
Frequently Asked Questions
How much space do I need for a double shower with two shower heads?
For genuine comfort, 160 × 90 cm is the minimum we’d recommend. You can do it at 120 × 90 cm with opposing heads, but it’s a tight fit. Below 120 cm wide, we wouldn’t bother.
Will I have enough water pressure to run two shower heads at the same time?
It depends entirely on your installation. Two rain heads running simultaneously demand a significant flow rate. In most cases you’ll need to inspect the supply pipework and, quite often, reinforce it. Check before you buy the fittings.
Do I need two thermostatic valves, or will one do?
For independent temperature control, you need two. With a single thermostat you’ll have two jets, but at the same temperature — and that means losing the main advantage of a double shower. If the budget is tight, save money elsewhere.
Does a double shower use a lot more water?
Per session, yes — you have two jets open. You’ll compensate by spending less time with the bathroom occupied overall. It’s not a water-saving solution; it’s a convenience one. If reducing consumption is your priority, look at low-flow options on a single head instead.
Does it add value to the property?
It’s a genuine selling point in a well-finished master bathroom, but you won’t recoup it euro for euro on the sale price. Think of it as an upgrade you’re making to enjoy while you live there, not a renovation investment in the property-flip sense.
In Short
A double shower with two shower heads is a genuine luxury — not a catalogue fantasy — provided you have three things in place: the space (160 cm minimum), plumbing that can handle two simultaneous jets, and two proper thermostatic valves. If those boxes are ticked, you’ll appreciate it every morning. If any of them is missing, a well-specified single shower will give you nearly the same experience without the extra cost.
