The classic argument for keeping an old cast iron clawfoot is that they’re built to last forever and don’t make them like that anymore. That’s true. But it’s not the whole picture.
Modern acrylic clawfoot tubs have gotten genuinely good. And in many situations — especially for buyers who aren’t driven by nostalgia — new acrylic is the smarter practical choice.
Here’s the honest comparison.
Why Acrylic Has Won Over a Lot of People
Weight. A standard 5-foot cast iron clawfoot tub weighs 250–350 lbs empty. Add water and a person and you’re asking a lot of your floor structure. Most floors in older homes handle it, but it’s a real consideration — especially if you’re doing a second-floor bathroom.
A comparable acrylic clawfoot tub weighs 70–100 lbs. That’s a one or two-person move rather than a four-person ordeal.
Installation. Lighter weight means you can DIY the install, or at minimum you’re not paying for a three-man crew. One or two people can carry an acrylic tub into place, set it on the legs, and connect the plumbing. Moving a cast iron tub requires planning.
Cost. A decent used cast iron clawfoot tub in need of restoration runs $500–$1,500 at salvage dealers and on Craigslist, before any restoration work. Professional refinishing adds $400–$700. New feet may add another $200–$400. You can spend $1,500–$2,500 restoring an old cast iron tub.
A new acrylic clawfoot tub that includes drain, overflow, and legs ships free from Amazon for $600–$1,200. You can be soaking the same day you install it.
Warranty. A new acrylic tub comes with a manufacturer’s warranty — typically 1–5 years. Your restored cast iron clawfoot comes with the previous owner’s confidence.
Modern features. New acrylic clawfoots often include built-in overflow and drain hardware, pre-drilled faucet holes in the right position for freestanding or deck-mount faucets, and sometimes slip-resistant surfaces inside the basin.
What to Look For When Buying
Not all acrylic clawfoot tubs are created equal. Here’s what matters:
Acrylic thickness. Look for a minimum of 8mm acrylic reinforced with fiberglass backing. Thin acrylic (under 6mm) flexes when you sit in it — the “creaking” and “giving” that some cheaper tubs produce. Thicker acrylic with proper reinforcement feels much more solid.
Legs included. Most reputable listings include legs. Confirm the leg finish matches your other fixtures. Adjustable legs (leveling feet) are a significant advantage on imperfect floors.
Drain and overflow included. Most complete kits include the drain and overflow in matching finish. If they’re not included, budget an extra $80–$150 for quality drain hardware.
Freestanding drain compatibility. Freestanding clawfoot tubs typically use a specific freestanding drain and filler (faucet) assembly. Confirm the tub has the correct pre-drilled holes for the filler style you want.
Basin depth and length. The interior basin size matters more than the exterior dimensions. A 59” tub may have an interior soaking length of only 45”. If you’re tall, verify the interior dimensions.

When Old Cast Iron Is Still Worth It
Cast iron has real advantages that acrylic doesn’t match:
Heat retention. Cast iron holds heat dramatically better than acrylic. If long, hot soaks matter to you, cast iron stays warm longer. Acrylic is a decent insulator but not cast iron.
Feel and weight. There’s something about sitting in a heavy cast iron tub that feels different — more substantial. Some people care about this.
Sentimental or historical value. If it’s your grandmother’s tub, or a documented antique piece, that value is real even if it’s not financial.
Ornate feet. Some original clawfoot feet are genuinely beautiful and specific to an era. A Victorian ball-and-claw foot from 1895 doesn’t look the same as a reproduction.
If any of these factors matter to you, restore the old one. The process works — a properly refinished cast iron clawfoot looks stunning.
If you’re making a purely practical decision with none of that emotional component, new acrylic is often the better investment.
The Bottom Line
If the old cast iron is structurally sound, the feet are intact, and you have a reason to keep it — keep it. Refinish it, get new feet if needed, and you’ll have a beautiful tub for another 20 years.
If the old one is heavily damaged, missing feet, or you’re just starting fresh in a bathroom renovation with no attachment to the existing tub — a new acrylic clawfoot is excellent value and a genuinely easy installation.
