What are good alternatives to a Kohler freestanding tub?

What do Kohler's published prices look like?

The spec sheets carry no prices, so the figures below come from kohler.com listings captured on January 15, 2026. The Volute (K-29329-7-0) showed $4,423.91 against a $5,898.55 list price. The Memoirs (K-8332-0) showed $6,068.77 against a $8,091.70 list price. No price for the Artifacts or Irvine was verified, and current prices should be checked on kohler.com.

Which makers sell freestanding tubs in the same materials?

Each maker below is described only by what it publishes itself. Weights and prices are as published on the dated pages listed under sources; not every maker publishes both.

Within cast iron, Waterworks sells the Voltaire and Candide, both with an enameled interior; the weight was not on the pages reviewed. For a resin or composite body, Badeloft describes its tubs as stone resin, a marble and limestone composite bound in resin. Aquatica calls its AquateX a solid surface made of about 60% aluminium mineral from bauxite with acrylic resins. Victoria + Albert describes QUARRYCAST as milled Volcanic Limestone blended with high-performance resins, with a 25-year residential guarantee.

What changes when you move to solid natural stone?

A solid natural stone tub is carved from one block, so every piece differs in veining and color, and the wall can be thick and heavy where an enameled or resin tub is thin. Stone is also sold in a different price tier: US sellers publish solid stone tubs at roughly $7,930–$37,000 as of October 2026 (see marble tub cost), and Waterworks lists its Ibla marble tub from $40,090.

• Stone versus acrylic: how the materials differ in weight, feel and care.
• Cast iron bathtubs: the closest metal-and-enamel comparison to Kohler's Volute and Artifacts.
• Stone resin versus solid stone: composite bodies compared with a carved block.
• Stone Forest alternatives: other makers of carved stone tubs.

How much heavier is a solid stone tub than a Kohler cast iron tub?

A solid stone tub weighs about 1,100–2,500 lb empty, against 407 lb for the Kohler Volute and 396.2 lb for the Artifacts, so roughly three to six times as much. Water adds 500–900 lb on top. A typical 67 x 31 x 22 in oval marble tub with 2.5 in walls comes to about 1,150 lb empty and about 1,960 lb filled with a 200 lb bather, around 170 psf on its footprint, against 40 psf typical residential floor live load.

Kohler's own 61.2 lb/ft² floor-load figure for the Volute shows the question is worth asking for any tub. Have a structural engineer review the framing, and see the stone tub weight guide for the arithmetic by stone.

Who is a Kohler freestanding tub best for?

A Kohler tub suits buyers who want a catalog product with a published spec sheet, a stated floor load and a choice of materials from acrylic to cast iron. The figures a plumber and framer need are on the sheet, and the price is shown on kohler.com. If the brief is a specific model from a single manufacturer's range, staying with Kohler is the straightforward route.

Look beyond it when the goal is a one-off material: natural stone with its own veining, or a size outside the catalog. A licensed plumber and local code should confirm drain, supply and any floor-load requirements for any tub.

What does a Pietra Fonte quote include?

Pietra Fonte tubs are made to order from a single block of natural stone. Each piece is specified with the buyer or designer, inspected with photos and video before it ships, and delivered white-glove anywhere in the contiguous US. Every quote gives the exact dimensions and weight of the piece, so the structural conversation can start from real numbers. See the marble, travertine and onyx tub collections, or ask for a sample book. Designers and builders can use the trade page.
