Most people shopping for a new bathtub start with two numbers: 60 x 30, 60 x 42, 72 x 42. Those are the tub's length and width in inches, and they are the quickest way to narrow a search. They don't tell the whole story, though. A tub's real measurements, how it is installed and which end the drain is on all decide whether it fits. To build this chart, we sorted every alcove, drop-in and corner bathtub in our catalog by size on October 2, 2026: 390 listings from Atlantis Whirlpool, Anzzi and Lexora, with the actual dimensions, water depth and drain position each listing gives.
This guide covers built-in tubs. For tubs that stand on their own, see Freestanding Tub Sizes: What to Expect at Every Length. For tubs with a door, browse our walk-in tubs.
Sizes are length x width in inches. "Measures" is the range of overall dimensions in the listings at each size. "Models" counts every listing, so the same tub with a different jet package or drain side counts separately.

Water depth is the soaking depth given in each listing's specifications; "(15 of 17)" means 15 of the 17 listings at that size give it. Atlantis means Atlantis Whirlpool. Lexora's Provenza comes in 60 x 30 and 60 x 32, and Anzzi's Illyrian in 72 x 36 and 72 x 32, so each one is counted at both sizes. Twelve listings don't state an installation type (Anzzi's Illyrian and Alya, and nine Atlantis IndulgenceWaterfall ovals), so they are marked "not stated."
An alcove tub fits into a recess with walls on three sides, usually with a shower above it. Only the front is exposed, so alcove tubs come with a finished front, called a skirt or apron. Every alcove tub we carry is 60 inches long: the Atlantis Soho in 60 x 30 and 60 x 32 (12 listings: soaking, whirlpool or air), the Anzzi Saba in 60 x 30, and the Lexora Provenza in 60 x 30 or 60 x 32.
Planning a glass door instead of a curtain? The Vinnova Villena and Vinnova Spezia sliding tub doors are listed at 60" W x 58" H.
A drop-in tub is set into a deck, a framed platform that you build and finish with tile or stone. The tub's rim rests on top of the deck, so only the inside of the tub shows. Because the deck can be built to any shape, a drop-in tub isn't tied to a 60-inch opening. It can go into an alcove, along one wall or out in the room. Nearly every size in our catalog that is wider than 32 inches or longer than 60 inches is a drop-in tub, from 60 x 30 all the way to 84 x 43.
An undermount tub uses the same kind of deck, but the finished deck surface covers the rim. None of the listings in this chart describe an undermount installation, so if that's the look you want, contact us before you order.
A corner tub fits into a corner with an angled or curved front, which leaves the rest of each wall free. All 48 corner tubs we carry are 60 x 60 models (sometimes called 5-foot corner tubs): 46 from Atlantis Whirlpool and 2 from Anzzi. Atlantis lists its corner tubs as drop-in, so plan for a corner deck. We don't currently carry a 48 x 48 corner tub.
A tub's name uses round numbers (the nominal size). The measurements on the spec sheet often don't match exactly. A few examples from the chart:
The differences are usually an inch or two. The alcove tubs in this chart are all listed at exactly 60" long, and for a drop-in tub you can frame the deck to the real measurements, as long as you go by the spec sheet and not the name.
Stand outside the tub and face it. If the drain is at your left, it's a left-drain tub; if it's at your right, it's a right-drain tub. This matters most for an alcove tub, because the drain end has to line up with the drain plumbing under the floor, and the faucet and shower valve usually go on the wall at that same end.
Before you order, check the "Drain Location" line in the listing's specifications.
Overall height is how tall the tub is on the outside. Soaking depth is how deep the water can get before it reaches the overflow drain, and it is always several inches less. The Atlantis Venetian 3660VNDR (36 x 60) is a good example: 23" tall overall, 19.9" deep inside and a 15.9" soaking depth.
Across the chart, listed soaking depth runs from 13" (the Atlantis Soho 60 x 32) to 18.375" (the Atlantis Charleston 48 x 78). The 60 x 30 tubs list 13.5" to 14", and the 72 x 42 tubs list 14.625" to 17". A larger footprint mostly buys room to stretch out, not much deeper water. Listed capacity doesn't follow footprint closely either: several 60 x 60 corner tubs list 40 gallons, less than the 50 gallons listed for most of our 60 x 30 tubs.
For a truly deep soak in a small space, the stone resin Japanese soaking tubs we carry fill to about 24 inches; see our Japanese soaking tub guide. Before you choose a large tub, also check your water heater. The tubs here list 30 to 80 gallons, and our two-person bathtub sizing guide explains why heater size matters for a big tub.
Almost every size comes in four versions. Across the chart there are 58 soaking tubs with no jets, 84 with whirlpool (water) jets, 86 with air jets and 164 with both.
Our whirlpool vs. air jetted tub comparison explains how each type feels and how to keep it clean. Here is what's available at each size:

The Anzzi Saba and the Lexora Provenza 60 x 30 can be ordered with either drain, so they are counted under both left and right.
A 42 x 60 tub (also written 60 x 42) is 60 inches long and 42 inches wide. The 18 we carry are all Atlantis Whirlpool drop-in models. They measure 59.625" to 60" long and 41.5" to 42" wide, stand 23" tall and list a 16" soaking depth. Every 42 x 60 we carry is a drop-in tub, so it is installed in a deck rather than a standard 30- or 32-inch alcove. Example: the Atlantis Vogue 4260V 42 x 60 soaking tub.
Not a 60-inch one. A 72 x 42 is 12 inches longer and 10 to 12 inches wider than a 60 x 30 or 60 x 32, and every 72 x 42 we carry is a drop-in tub, so it needs space for the tub plus its deck. The 57 models measure 70.75" to 72" by 41" to 42.25" and stand 23" tall. Example: the Atlantis Venetian 4272VN.
60 x 30 is the size most people mean by a standard tub. We carry 17: 8 alcove tubs with a built-in front skirt and 9 drop-in models, with listed soaking depths of 13.5" to 14". If you have 2 more inches front to back, 60 x 32 gives you 34 models to choose from.
A 48 x 60 tub is 60 inches long and 48 inches wide. We carry 9, all Atlantis Whirlpool drop-in models from the Neptune and Rhode lines. They measure 59.5" to 60" by 47" to 47.25" and list a center drain, a 15" soaking depth and 65 gallons. Example: the Atlantis Neptune 4860N.
Face the tub from outside it: if the drain is on your left, it's a left drain. If you're replacing an alcove tub, match the drain side you have unless you plan to move the plumbing. At 60 x 30, 9 of our models are available with a left drain and 9 with a right drain.
Yes. Of the 37 models we carry at 60 x 36, 8 have whirlpool jets and 16 combine whirlpool and air jets. All are Atlantis Whirlpool drop-in tubs, rectangular or oval, measuring 59" to 60" by 35.5" to 36". Example: the Atlantis Venetian 3660VNWL.
It is sold as a 5-foot (60 x 60) corner tub, but check the listing: ours give overall dimensions of 82" to 85" by 61.5" to 67.125". Eight of our 48 corner tubs are soaking tubs with no jets, including the Atlantis Cascade 6060C and the Anzzi Petra, with listed soaking depths of 14.25" to 17.125".
Yes, 7 of the 57: the Atlantis Vogue 4272V and 4272VC, Venetian 4272VN and 4272VNC, Polaris 4272P, Eros 4272E and Whisper 4272W. Their listed soaking depths run from 14.625" to 16.5".
Not at the moment. Every corner tub in our catalog is a 60 x 60 model. For a smaller space, our Japanese soaking tubs start at 39 inches long.
Browse all bathtubs, or shop by type and size: alcove bathtubs, corner bathtubs, 60 x 42 bathtubs and 72 x 42 bathtubs. By brand, see the Atlantis Whirlpool collection for most of the sizes above, Anzzi soaker bathtubs for the Saba, Illyrian, Alya, Petra and Rana, or Lexora for the Provenza. The wider jetted models and the jetted corner tubs are also grouped in our two-person jetted tub collection. If you'd like a second look before you order, send us your measurements and the model you're considering, and we'll check them against the spec sheet.
