Description

A compact oval tub with a smooth Solid Surface Stone body and three finish options.

OBSIDIAN keeps the quiet, rounded presence of a full-size oval bath in a more compact 59-inch footprint. It is sized for smaller bathrooms, guest suites, and remodels where the tub still needs to feel intentional rather than squeezed in.

The Solid Surface Stone body gives it a substantial, matte feel with a seamless, non-porous surface that is easy to clean and comfortable to the touch. Its centered drain and balanced oval shape make it straightforward to place, while the 68-gallon capacity gives it enough depth for a real soak.

OBSIDIAN is available in Matte White, Dark Gray, and Matte Black. Choose white for the easiest everyday upkeep, or a darker finish when you want stronger contrast and a more architectural bathroom look.

Why Choose a Solid Surface Bathtub?

The water stays warm

The water stays warm

The most common regret with a freestanding tub is that the bath goes cold before you're ready to get out. Thin acrylic sheds heat to the room fast — a soak can turn lukewarm inside twenty minutes unless you keep topping it up. Solid surface is dense. It draws very little warmth out of the water as you fill, then gives back what it holds slowly, and the tub itself feels warm against your back from the first minute instead of cold.

Scratches sand out

Scratches sand out

The colour runs through the full thickness of the material, not just across the surface. Mark it, and you work it back with the fine sandpaper in the box — what's underneath is the same colour. On acrylic, damage that goes through the gel coat is permanent. Five years in, that's the difference between a tub that still looks new and one you've stopped showing people.

Solid underfoot, and not slippery

Solid underfoot, and not slippery

Moulded as a single piece on a wide base, there's no flex and no wobble when you step in. The matte surface has a fine texture that grips wet or dry, so there's no applied anti-slip coating to wear off over time.

Seamless, non-porous, easy to keep

Seamless, non-porous, easy to keep

No joins, no seams, no silicone lines inside the tub. The surface doesn't absorb water, so soap film and limescale wipe off rather than working their way in, and there's nowhere for mould to take hold. It's stable enough for a sunroom or a covered outdoor setting, not just a bathroom.

BEFORE YOU ORDER

Checks before you order

Confirm the route in, drain position, and everyday fit before delivery day.

The route in.

At 29.5 inches wide, OBSIDIAN clears a standard 30-inch interior doorway, but measure the tightest hallway turn and stair landing before ordering.

Your space.

The 59-inch length is best for compact bathrooms, guest suites, and remodels where a longer tub would crowd the room.

Your waste pipe.

OBSIDIAN uses a centered drain, so it is most straightforward when replacing another center-drain tub.

Which finish.

Matte White is the easiest to keep looking clean. Dark Gray and Matte Black create a stronger design statement but show water spots more readily.

BUYING & CARE GUIDE

OBSIDIAN Bathtub FAQs

Helpful answers for choosing, installing, and caring for your new bathtub.

Is OBSIDIAN acrylic?

No. OBSIDIAN is made from Solid Surface Stone, the same material family as the other INYOUTHS solid surface bathtubs.

Is Dark Gray harder to look after?

It is not harder to clean, but it shows water spots and soap film more readily than white. A quick rinse and wipe after use keeps the finish even.

Will it fit through a standard doorway?

The tub is about 29.5 inches wide, so it clears many standard 30-inch interior doors. Always measure the tightest turn, hallway, and stair landing before ordering.

Is it good for a smaller bathroom?

Yes. The 59-inch length is designed for compact bathrooms where you still want the look and comfort of a freestanding oval tub.

Does it hold heat well?

Yes. Solid Surface Stone is dense and warm to the touch, helping the bath water cool more slowly during a soak.

Do I need a plumber?

A plumber is recommended, especially if your drain needs to be moved. The tub includes the drain assembly and cover, but the tub filler and drain pipe are sold separately.

Can I use my existing faucet?

Only if it is floor-mounted or wall-mounted. OBSIDIAN does not have deck-mounted faucet holes on the rim.

Is the surface slippery?

No. The matte surface has a fine texture that grips underfoot when wet or dry, without feeling rough.

Can it go on an upper floor?

In most modern homes, yes, but confirm the route and floor support with your contractor before delivery, especially in an older house.

What if it arrives damaged?

Photograph the crate before opening, contact us within 48 hours, and keep the packaging. We will help arrange a replacement or next step.
