ᐅ Make an oval-shaped bathtub slightly movable due to dirt buildup behind it?

Hello everyone,

we are currently planning our home renovation and thinking about the bathroom. We have already consulted a specialist on this.

We find a freestanding oval bathtub very stylish, but the advisor recommended against a design-focused tub due to the intended corner position. The reason is that dirt would accumulate behind it, making it difficult to keep that area clean and dry.

I’ve been thinking about this and appreciate that he was honest about these issues.

Furthermore, we use the bathtub only about 15 times a year; the rest of the time it would either collect laundry or just be wasted space. Also, the main problem seems to be the fixed bathtub itself and the resulting difficulty in cleaning behind it.

Therefore, I came up with the idea that the bathtub could be made movable somehow (with small/flat casters or something similar). The only real issue here would be the drainage of the used water.

So here is the idea I have in mind:

  • We equip the bathtub with small/flat casters or similar so it can be moved forward for cleaning.
  • Option A – Attach a hose to the drain so that after use, the hose can be placed in the shower to allow the water to drain there.
  • Option B – Use a flexible drainage system so the bathtub can be moved for cleaning with the drain attached.
  • Optionally, consider whether a bathtub faucet is needed at all, or if just a showerhead mounted on the wall would suffice (currently, we also fill the tub exclusively using the shower hose).

Below is a rough plan showing our current bathroom layout. The measurements are accurate, but the walls are not to scale. Speaking of measurements, we are quite short at 155cm (5 feet 1 inch) and 168cm (5 feet 6 inches) and can manage fine with a somewhat smaller bathtub. Guests or children are not a priority for now ;-)

What do you think about our plan? The dimensions for both bathtub and shower are 165cm (65 inches) each, which should just fit.. We still need to try lying in the bathtub to be sure :-/

Thanks in advance to everyone who advises us & best regards

Aside from that, "impossible" does not exist.

But do you really want it that way?

You will hardly find a plumber who will carry it out for you, mainly due to liability and warranty issues.

My bathtub is 1.65 m (5 ft 5 in), so either the knees or the shoulders stick out of the water. I am 1.80 m (5 ft 11 in).

My bathroom design software starts with freestanding bathtubs at 1.8 m (5 ft 11 in).

For example, I would replace the window on the left with a 90 cm (35 inch) door and permanently glaze the rest on the right.

If the plumbing is still free to plan, which I doubt in an existing building, then the entire bathroom should be redesigned. You will surely get help with that here as well.

Here is my first proposal. A version with a rotated shower will follow.

Floor plan of a room: red furniture on the left, red cabinet, blue oval rug on the right, door at the bottom.


Modern bathroom with red wall, freestanding bathtub, and view of green meadows and mountains.


Bathroom with red wall, double sink, shower on the left, window with landscape view.

Here is the second version with a walk-in shower.

Floor plan of a room with a door at the bottom, window on the right, red furniture on the left, desk on the right, plant.


The bathtub can only be 1.8 m (5 ft 11 in) with this design.

The window on the right is fixed glazed.

The pivot mechanism has been removed. Cleaning is easy.

The view from the window is unobstructed. 😉

I would definitely try a tub like that. My wife is 162 cm (5 ft 4 in) tall, and she can barely get in and out of most freestanding tubs because of their high sides. In the end, we decided on a standard bathtub.

A corner bathtub works too, but it doesn’t look as stylish.

3. Align the empty tub.
4. Position the hose so that it leads to the shower drain or another drain.
5. Fill with water via the showerhead.
6. Person gets out of the tub, pull the plug → water drains.
7. Rinse the tub out, water also flows into the drain.
8. If possible, clean behind the tub.
9. Return the empty tub to its starting position.

So you want to use an adult bathtub like an infant’s baby bath, fill it through the shower hose, and drain it through the built-in floor drain beneath it ;- (

I don’t understand!

Even a hippopotamus with its large mouth has to swallow when drinking. Emptying the tub by pulling the plug in one go will release a surge of water exceeding the capacity of the drain. Your plan will only work if the plug is carefully lifted in a controlled manner.

Even if the tub is moved without being filled, the castors will have to carry and transfer its full weight, not just when empty. For this, the tub won’t have suitable bearing points but rather expects an installation scenario providing a larger support area to bear the full weight. Point loads are generally not accounted for in the product’s structural design. Moving it while empty might be possible with chair-style castors—heavy-duty castors would likely require at least 8cm (3 inches) of overall height—small wheels comparable to those under an under-bed storage container definitely won’t suffice.

Well, I doubt any plumber would even see this setup as described being used in practice.

Go ahead and try the stunt—but be sure to report back your results! After all, every good Villa Kunterbunt deserves a monkey and a horse 🙂
