Available in rectangular and custom shapes, Onyx lavatories are made-to-order to meet the needs of your bathroom space.

Lavatories are available in almost any size, shape, and can incorporate any of our bowl styles, and edge styles.

A single bowl or multiple bowls can be located where needed. A backsplash can be integral (4” tall or less) or separate (any height). Faucet hole(s) frequently are for a single hole, 4” centerset, or 8” spread, but can be custom sized or located as you need, including an extra hole for a soap dispenser.

Very complicated shapes may require a Template. To learn about making Templates, click here

Lavatory Drain Recommendations

We recommend using tapered-thin drains – see comparison below


Flat-thick Drain vs. Tapered-thin Drain

Angled-thin Drain

Tapered-thin Drain is flush with the lavatory bowl and tapers down to allow the water to flow

Flat-thick Drain

Flat-thick Drain is flat which causes it to trap
water around the drain
