Depth Requirements
Most laundry tubs are 12 to 14 inches deep. Shallower basins cause splash-out and drain slower under heavy use. Deeper tubs handle mop buckets and utility rinsing without issue.

About Twin City Pipeworks
Why Homeowners Trust Us for Laundry Tub Replacement
Replacing a laundry tub sounds straightforward, but a bad connection at the supply lines or drain can mean water working its way into your subfloor for months before you notice. Twin City Pipeworks replaces laundry tubs in the east metro and St. Croix Valley, working with your existing supply and drain connections to make sure everything is properly sealed and draining correctly. We back every replacement with a 1-year warranty on all work, and we give you upfront, per-task pricing before we touch a thing. Book online to get on the schedule and we'll tell you what it takes.
What drives the cost on a laundry tub replacement depends on what we find with your existing connections. A straightforward swap where the shutoff valves are in good shape and the drain is clear is a much simpler scope than one where the valves are corroded, the supply lines are deteriorated, or the trap and drain arm need to be rebuilt. Tub size and whether it's a cabinet or freestanding mount also factor in. Labor and materials combined typically run $300 to $800 depending on what we find. Every job is different, and we give you upfront, per-task pricing before any work begins.
What a Complete Laundry Tub Replacement Actually Covers
We don't just 'hook it up' and leave. Every replacement starts with a look at what you've got: existing shutoff valves, supply line condition, drain elevation, and whether the current trap and drain arm are in serviceable shape. Old shutoff valves that are corroded or stiff get replaced at the same visit so the new tub isn't sitting on 20-year-old valves. We set the tub level, secure it to the wall or cabinet, connect supply lines with proper shutoffs, and test for leaks before we're done. If you need a faucet or fixture looked at while we're already in the laundry room, we handle that in the same visit. No second trip, no loose ends.
Can a Washing Machine and Laundry Sink Share the Same Drain?
Yes, if the drain is sized and vented correctly. A 2-inch standpipe is the standard for a washing machine. A laundry tub on the same drain line works when the pipe diameter supports the combined flow and the vent is adequate. The mistake we see most often in existing setups is a sink drain teed into the washer standpipe without enough pipe diameter, which creates back-pressure, slow draining, and gurgling. When we replace a laundry tub and your washer shares the same drain, we inspect the existing drain configuration and tell you honestly whether it can handle the load. The cheap shortcut almost always costs more to fix later.
Why Twin City Pipeworks
Key Facts About Laundry Tub Replacement
Here's what you need to know before the work starts:
Supply Line Specs
We check your existing hot and cold shutoff valves and supply lines as part of every replacement. If the valves are corroded or stiff, we replace them at the same visit so the new tub sits on connections you can actually rely on.
Venting Requirements
Every drain fixture in Minnesota needs to be vented. An unvented laundry tub drain will gurgle, drain slowly, and can siphon the trap dry. We tie into the existing vent stack or add an air admittance valve where code allows.
Code Compliance
Minnesota Plumbing Code requires proper pipe sizing, fixture units, and trap installation. We make sure the finished replacement meets code, so it doesn't become a problem at resale.
Washer Connections
If your washer supply or drain connections also need attention while we're already in the laundry room, we can look at those in the same visit. Combining scope saves you a second service call.
1-Year Warranty
Every laundry tub replacement Twin City Pipeworks completes is backed by a 1-year warranty on all work. If something leaks or fails due to our work, we come back and fix it. No arguments.
When to Call a Plumber vs. Try It Yourself
Replacing a laundry tub that sits on functional supply and drain connections is one of the more manageable DIY plumbing jobs. Shut off the valves, disconnect the supply lines, unthread the drain tailpiece, swap the tub, reconnect. If the connections are in good shape and you're comfortable with basic plumbing, it's doable. Where we get called in is when the shutoff valves are seized and fail the moment someone tries to turn them, when the drain trap is corroded and breaks during the swap, or when the new tub's configuration doesn't match up with what's there. We've fixed enough botched DIY laundry tub swaps to say this plainly: the job looks simple until the first valve turns and everything goes sideways. Book online to get on the schedule if you're not sure what you're looking at, or call or text (651) 247-4495.

Frequently Asked Questions
How deep does a laundry tub need to be? +
The standard recommendation for a utility laundry tub is 12 to 14 inches deep. Shallower basins splash during heavy rinsing and tend to drain slower because they sit flatter. Most freestanding utility tubs sold today fall in the 12 to 14-inch range, which gives you enough capacity for mop buckets and hand-washing without creating a drainage bottleneck. If you're in a tight space, a shallower tub can work, but expect to manage the flow rate carefully.
Can a washing machine and sink share the same drain? +
They can share a drain, but the pipe needs to be sized to handle both fixture units and the vent stack has to support the combined load. The standard setup uses a 2-inch drain with a proper trap and vent. Where we see problems is when someone tees a sink drain directly into the washer standpipe without upsizing the line. That creates back-pressure, slow draining, and gurgling. Done correctly with adequate pipe diameter and venting, sharing a drain is code-compliant and common.
What do I need for a laundry tub replacement? +
A laundry tub replacement needs working hot and cold shutoff valves, supply lines, a P-trap, and a functioning drain connection at the correct elevation. In Minnesota, the vent connection is required by code. Before you buy the replacement tub, confirm the new tub's drain configuration matches what you have, and check whether your existing shutoff valves are in serviceable condition. Corroded valves that haven't moved in years often fail when you try to shut them off for the swap.
How hard is it to replace a laundry tub? +
A straight replacement on a tub with functioning supply and drain is manageable for a capable DIYer. If you're replacing like-for-like and the existing connections are in good shape, it's reasonable to DIY. Where things get complicated is when the shutoff valves are frozen, the drain trap crumbles during removal, or the new tub's hole spacing doesn't match the existing faucet connections. Any mistake in drain slope or trap installation shows up immediately as slow drainage or gurgling. If you run into those problems mid-job, it's worth calling a licensed plumber rather than improvising.
Do I need a permit to replace a laundry tub in Minnesota? +
A simple like-for-like replacement of an existing laundry tub using the current supply and drain connections typically does not require a permit in Minnesota. We make sure all finished work meets Minnesota Plumbing Code before we close out the job.
Can Twin City Pipeworks handle the washer connections and laundry tub in the same visit? +
Yes. If your washer supply valves or drain connections also need attention, we can look at those in the same visit as the laundry tub replacement. Handling both at once saves you a separate service call and keeps the total labor cost lower than scheduling them separately. Let us know when you call what you need so we arrive prepared with the right parts.
