This is our main floor bathroom, and the only bathroom in the house with a tub

Can you move the plumbing easily? A scaled drawing with ALL dimensions and plumbing locations currently will help you get advice.

There are no circumstances where squeezing in a mobile home sized tub into a shower, just to have one, will ever work.

All the plumbing other than the toilet is moveable

Please take a look at our proposed layout for the plumbing in this bathroom.

We recommend placing the bathtub and shower not parallel to each other, because doing so creates a “train car” effect in a small space making the room feel too narrow and elongated.

To avoid that, we suggest rotating the bathtub — everything still fits very well. You can even install a double sink, or, if you prefer more free space, use a single sink and add a small storage cabinet. Access to both the bathtub and the shower remains open and convenient.


The layout is functional and considers the needs of all users.

You can go with a double sink,
or choose a single one:
which will free up space for a cabinet where you can store essentials,
if that’s important to you. Also, consider placing a freestanding towel holder between the bathtub and the shower —
it will be convenient whether you’re stepping out of the bath or the shower.

Also, keep in mind:
if you position the shower enclosure to the right, close to the entrance,
you won’t get the feeling of walking into a narrow or cramped space because the largest element will be behind you,
not directly in your line of sight. This creates a more open and comfortable entrance experience.

We are spatial planning experts — here are our key recommendations:

The bathtub and shower should not be placed parallel:

-- This creates a “train car” effect and visually narrows the space.

We recommend rotating the bathtub:

-- Everything still fits well, and the layout becomes more balanced.

Sink options based on your priorities:

-- Double sink — ideal for two-person comfort.

-- Single sink + storage cabinet — a better choice if maximizing space is important.

Maintain clear and open access:

-- Both the bathtub and shower remain easy to reach and convenient to use.

Place a freestanding towel holder between the bathtub and the shower:

-- Accessible from either side — practical and elegant.

Position the shower near the entrance (on the right):

This keeps the largest element (the tubshower) behind you, creating a visually open and welcoming entry.

I like your idea with a tub/shower, extra storage and a single sink vanity to give you more drawers.

If the tub is in a corner like that IMO it should be a drop in. It will be hard to clean around it and hard to get in and out with those clearances

Not enough room to do that. A 54” tub is a terrible choice to inflict on anyone. A main bath should have at least a 66” tub, if you are going to have a tub. With a foot of clearance all the way around.

You have enough room for a nice sized shower. And that is it.

This will be the best layout option for you. But you have to move the toilet.

- It allows for a full-sized bathtub and a spacious walk-in shower.

- You’ll just need to reposition the toilet.

- To hide the toilet plumbing, we suggest adding a built-in storage cabinet.

- The toilet can also be wall-mounted with a concealed installation, if you prefer a more minimalist look.
