Every pipe, fitting and fixture. Counted.
From a toilet or water heater swap to a bathroom rough-in: StudSheet sizes the drains and vents by fixture units, counts the pipe, fittings, valves and connectors with the math shown and the code notes, then prices it for an estimate the client signs on the spot.
The plumbing Sheets
- Plumbing rough-in: drain fixture units under the IPC, the UPC or Canada’s NPC; drains and vents in PVC, ABS or cast iron, tied into the existing stack or a new one; water lines in PEX-A, PEX-B, copper or CPVC, as trunk and branches or a manifold.
- Water heater replacement: a gas or electric tank, gas tankless or a heat pump, atmospheric, power or direct vent, with the expansion tank, relief line, connectors and permit.
- Replace a toilet: two-piece, one-piece or wall-hung, a wax or wax-free seal, the flange checked, new bolts and supply line.
- Replace a bathroom vanity and a faucet: the fit, the supply lines, the trap and the sealant.
From the plumbing Sheet: 3 fixtures
3 fixtures: 5 drain fixture units, a 3″ drain branch, 1½″ vents and ¾″ + ½″ water lines, every fitting counted.
| Buy | Item | How StudSheet counts it |
|---|---|---|
| 6 × 10′ lengths | PVC DWV pipe, 1½ in | vent for 1 toilet 6 ft + 1 lavatory 4 ft + vent for 1 lavatory 6 ft + 1 tub/shower 5 ft + vent for 1 tub/shower 6 ft + vent header 20 ft = 47 ft, + 10% for cuts → 6 × 10′. |
| 3 × 10′ lengths | PVC DWV pipe, 3 in | 1 toilet 4 ft + branch 20 ft = 24 ft, + 10% for cuts → 3 × 10′. |
| 27 fittings | DWV fittings, 1½ in (PVC or ABS) | Allowance: the trap or bend, tees and elbows at each fixture (3–4), 3 per vent, a wye or combo per fixture on the branch, long sweeps, and a coupling between lengths. |
| 10 fittings | DWV fittings, 3 in (PVC or ABS) | Allowance: the trap or bend, tees and elbows at each fixture (3–4), 3 per vent, a wye or combo per fixture on the branch, long sweeps, and a coupling between lengths. |
| 2 pint sets | PVC primer and cement (pint set) | About 130 joint-equivalents (a 3″ joint takes about 2½ times the cement of a 1½″ one); a pint does about 90 of the small ones. |

Questions
Can I price a fixture swap on the spot?
Yes. Open the toilet, faucet, vanity or water heater Sheet at the client’s house: your price book prices the fixture, the parts and your labor, the client signs on your phone, and you record the deposit or the full payment before you leave.
What size water heater for a family of four?
It goes by the busiest hour, not the head count. Four showers in an hour come to about 83 gallons, which a 50-gallon gas tank with an 84-gallon first-hour rating covers. The water heater Sheet works it out from your household and checks the vent.
