The humble bathtub overflow is a small part with a huge job: preventing water damage, meeting plumbing code, and giving homeowners peace of mind. When you install bathtub overflow assemblies correctly, you protect subfloors, finishes, and client relationships. At CountBricks, we combine AI-driven estimating, voice-activated workflows, and instant material databases to make every residential installation faster and more profitable.
• Water intrusion is the leading cause of warranty callbacks in bathrooms
• Incorrect gasket compression can void tub manufacturer warranties
• Local inspectors often target overflow height and trap arm slope for code compliance
• Homebuyers equate plumbing details with overall build quality—one leak can erode trust
• Time lost hunting for up-to-date pricing on brass vs. PVC kits
• Unclear labor allowances when the tub is set in tight alcoves
• Blueprint discrepancies that create on-site guesswork
• Manual data entry that delays invoicing and cash flow
Real-time voice capture—Dictate measurements while you’re in the bathroom; our AI adds them directly to your estimate.
Live material costs—CountBricks syncs with national suppliers every hour, so your brass, PVC, or ABS overflow kit pricing is always current.
Automated blueprint takeoffs—Upload the plan, tag the tub symbol, and our platform counts every overflow assembly required in seconds.
Instant labor benchmarking—Our residential construction database adjusts man-hours for alcove, drop-in, or freestanding tubs with one click.

1. Measure and mark: Confirm rough-in height and centerline from the blueprint generated by CountBricks AI takeoff.
2. Dry fit the waste shoe: Place gasket inside the tub, align the shoe from beneath, and hand-thread the flange.
3. Assemble the overflow: Attach the tee, cutting pipe to length per the AI-generated material list.
4. Secure the faceplate: Apply the supplied gasket, screw the plate until snug—avoid overtightening to prevent cracking the tub wall.
5. Connect to the trap: Slope the arm 1/4" per foot toward the drain as highlighted in your CountBricks code checklist.
6. Water test: Plug the tub, fill to overflow height, then inspect beneath for leaks before closing the wall.
• Use silicone on acrylic tubs; rely on rubber gaskets only for cast-iron models
• Label brass kits with a marker during rough-in to prevent finish mix-ups later
• Keep a telescoping inspection mirror in your pouch—it’s faster than lifting the tub skirt
• Photograph every connection; CountBricks automatically uploads images to your project file
• Schedule a second water test after tile installation to catch vibration-induced leaks
