CountBricks: Replacing a Bathtub Drain Assembly in Homes

James Miller
Head of Sales

Why Homeowners Search for “Replacing a Bathtub Drain Assembly”

Few fixtures work harder in a home than the bathtub drain. Constant exposure to water, soap scum, hair, and cleaning agents leads to corrosion or slow-drain headaches. When simple snaking no longer works, replacing a bathtub drain assembly becomes the best route to restore performance and protect subfloor framing from moisture damage.

How CountBricks Streamlines the Process

Traditional drain replacement quotes involve on-site tape measures, manual pricing books, and follow-up phone calls. CountBricks removes that friction with AI voice capture and real-time databases:

• Speak the scope into your phone—our AI instantly generates itemized labor, material, and permit costs.

• Drag-and-drop blueprint PDFs for automated takeoffs that flag exact pipe lengths, trap locations, and floor joist penetrations.

• Receive a branded quote document in minutes, ready for homeowner approval and e-signature.

When Is It Time to Replace Instead of Repair?

1. Recurring leaks around the shoe gasket or overflow plate.

2. Chrome finish has peeled, exposing rusted brass or steel.

3. Drain threads stripped, preventing a watertight seal.

4. House is being prepped for sale and inspectors flag sub-standard drains.

CountBricks estimators factor these red flags into ROI discussions so clients spend wisely.

Materials Selection: What Goes into the Estimate?

Drain Body & Stopper Style

• Classic lift-and-turn—budget friendly

• Push-to-close—sleek, tool-free maintenance

• Cable-operated—premium spas or deep soaking tubs

Pipe Composition

• PVC: economical, easy solvent welding

• ABS: ideal for colder Iowa winters due to thermal shock resistance

• Brass: long-life upgrade often paired with cast-iron tubs

Live price feeds inside CountBricks ensure your quote reflects today’s regional supplier costs instead of last quarter’s catalog.

Step-by-Step Field Procedure

Preparation

1. Shut off water to the tub.

2. Remove trim kits and old stopper.

3. Place protective blankets over porcelain to prevent chipping.

Removal

4. Use a drain key to back out the strainer body.

5. Cut the overflow linkage and detach the shoe.

6. Inspect adjacent framing for mold—CountBricks automatically adds remediation line items if needed.

Installation

7. Dry-fit new assembly, confirming slope to the P-trap (¼ in. per foot minimum).

8. Solvent-weld or thread connections per code.

9. Torque strainer body against fresh plumber’s putty.

Testing

10. Fill tub and perform a five-minute static test.

11. Drain while flashlight-inspecting below for weeps.

12. Photograph results—images sync to CountBricks cloud for client transparency.

Code Compliance and Permitting in Des Moines

Local residential plumbing code mandates 1-1/2 in. diameter for bathtub waste lines and approved trap primers where required. CountBricks software cross-checks each estimate against municipal amendments so your permit set is accurate the first time.

Budget Breakdown Example

• Labor (2 hours master plumber, 1 hour apprentice)

• Materials (PVC drain kit, chrome trim, solvent, sealant)

• Disposal fees for removed assembly

• Permit filing and inspection escort

Total: $425–$610, updated live through CountBricks pricing engines. View additional scenarios at CountBricks.com/portfolio.

Common Mistakes DIYers Make

• Over-tightening the strainer and cracking enameled steel tubs.

• Forgetting to align the overflow gasket, triggering leaks inside the wall cavity.

• Mixing ABS and PVC without the correct transition cement.

CountBricks pros eliminate these risks while providing warranty coverage.

Case Spotlight: Two-Hour Drain Swap Cuts Costs 18%

A recent CountBricks client, the Johnson family in West Des Moines, struggled with recurring ceiling stains below their master bath. Our estimator used a smartphone to narrate the problem during a walkthrough. Within 90 seconds, CountBricks generated a line-item quote that included:

• Removal of corroded cable drain

• Installation of a push-to-close brass assembly

• Minor joist sistering due to moisture damage

Because the AI flagged code-required access panel relocation automatically, no mid-project change orders were needed. The crew finished in two hours. Final invoice: $482—18% lower than the paper-based quote the homeowner received from another contractor the week prior.

Four Pro Tips for Faster, More Profitable Drain Replacements

• Pre-load your preferred material library in CountBricks so voice estimates pull exact SKUs instantly

• Use the mobile blueprint tool to capture subfloor thickness—this ensures the shoe gasket depth is correct on the first try

• Attach completion photos in the field; CountBricks auto-stamps time and GPS, reducing warranty disputes

• Convert the estimate to an invoice with one tap; homeowners can pay via secure link before you leave the driveway

Expanding Beyond the Bathroom

Replacing a bathtub drain assembly is often the gateway to broader upgrades. With CountBricks you can clone the original estimate and add:
