Custom Sinks & Bathtubs for Luxury Interiors

Vast Studio builds from the brief. Every tub and sink starts with your dimensions, your color, your finish, and your vision.

Luxury Custom Bathtubs

A luxury bathtub should do more than look impressive. It should retain heat, feel warm to touch, install without structural headaches and carry the exact finish you specified.

Our custom bathtubs are available in oval, round, slipper, and bespoke forms. We offer oval freestanding tubs, slipper tubs, and fully custom silhouettes built to your dimensions. Each includes our integral overflow system, built into the mould itself, and a matching engraved pop-up drain.

Luxury Custom Bathroom Sinks

Our luxury sinks are made to the same standard as every tub we produce. Custom bathroom sinks in any dimension, any finish, any color. Single-hole configurations, vessel forms, undermount options. The same lightweight reinforced concrete bathtub construction, applied to a piece built for everyday use at the vanity.

Why Choose Bespoke Bathroom Fixtures?

Because the alternative is designing your bathroom around what someone else decided to manufacture.

Off-the-shelf fixtures force compromise. The dimensions are close but not right. The finish is similar but not exact.

Bespoke changes the sequence. You decide the form, the color, the texture, and the scale. The fixture is built to those specifications, not the other way around.Custom bathroom sinks and tubs built from premium materials to precise specifications perform better over time than mass-produced alternatives.If your custom bathroom deserves to be finished properly, the fixtures need to be part of that thinking from the start, not sourced afterwards.

Our Bespoke Bathtub & Sink Design Process

You bring the brief to us, including dimensions, intended finish, interior color, exterior texture, and any specific requirements around installation. We consult, refine, and confirm the specification before anything is made.

Every piece is then handcrafted in Los Angeles. The lightweight reinforced concrete is formed, finished, and Pantone-matched to your specification, inside and out. We don’t rush this. Custom work has a lead time for a reason.

What you receive is a finished piece, not a flat-pack. Your custom bathroom sinks and bathtubs arrive ready for installation, complete with matching pop-up drain and engraved hardware.

Frequently Asked Questions

What is the lead time for a custom bathtub and sinks?

Lead times vary depending on complexity and finish specification. Because every piece is made to order in Los Angeles, we don’t hold stock. Contact us directly with your brief and we’ll give you an accurate timeline.

Can I choose my own dimensions for a custom sink and bathtubs?

Yes, entirely. Every Vast Studio piece is built to your specified dimensions. There are no standard sizes we’re working around. Whether you’re specifying a custom vanity top, a bathroom sink for an awkward alcove, or a bathtub for an oversized wet room, the dimensions start with you.

What materials are available for bespoke bathtubs?

Our core material is lightweight reinforced concrete made from organic, locally sourced components, produced entirely in the USA. Exterior finishes include hand-troweled plaster, textured concrete, and various applied metals. All materials are body-safe and selected with everyday use in mind.

What types of custom sinks and bathtubs are available?

We produce freestanding bathtubs in oval, round, and slipper forms, as well as fully custom silhouettes. For bathroom sinks, we work across vessel, undermount, and drop in sink configurations, including single hole options and designs intended for custom vanity integration.

Who should choose custom bathtubs and sinks?

Homeowners who’ve already rejected the catalog. Architects and interior designers specifying a bathroom space where the fixture needs to carry the room, not just occupy it. Hospitality and development clients who need each bathroom to feel distinct. If the standard options aren’t right, they’re not going to become right.
