Most tile contractors undervalue their time. If you're running one crew, building shower pans the old way, and pricing jobs at industry standard, you're probably leaving $10K–$15K a month on the table. Not because you're doing anything wrong — because the math of a 2-day install caps your monthly capacity.
Here's what one extra install per week is actually worth, and what it takes to get there.
The mortar-bed baseline
Take a one-crew operation building residential showers the traditional way:
- Per-shower time: 2–3 days (mud bed cure, waterproofing, tile)
- Weekly capacity: 2 showers (conservative — 5 working days, 2.5 days per shower with overlap)
- Monthly capacity: ~8 showers
- Average per-install revenue: $3,500 (labor + materials, residential standard)
- Monthly revenue: ~$28,000
That's the ceiling without hiring more crew or adding trucks. You'd have to scale operations to grow.
The 1-day install scenario
Now run the same crew with a 1-day install workflow — pre-sloped tray, waterproof membrane, drain, all from one kit:
- Per-shower time: 1 day (drop tray, waterproof, flood-test, tile next morning)
- Weekly capacity: 3 showers (room for travel, setup, prep)
- Monthly capacity: ~12 showers
- Monthly revenue: ~$42,000
That's +$14K a month from the same crew, the same truck, the same employees.
Where the +$15K really comes from
Conservative math: +1 install per week × $3,500 × 4.3 weeks/month ≈ +$15,050/month. We're not adding installs that wouldn't have closed — we're adding the ones you couldn't fit before because the calendar was full of cure days.
| Metric | Mortar bed | 1-Day Install |
|---|---|---|
| Days per shower install | 2–3 | 1 |
| Installs / week (1 crew) | 2 | 3 |
| Installs / month | 8 | 12 |
| Avg revenue / install | $3,500 | $3,500 |
| Monthly revenue | $28K | $42K |
| Added monthly revenue | — | +$14K–$15K |
The kit pays for itself on the first job
A full GURU Speedy Superkit runs $870–$1,067 depending on size and finish. That's less than 30% of a single $3,500 install. If 1-day installs let you fit one more shower per week, the kit is paid for in less than half of one job — and the rest is upside that flows straight to the bottom line.
You're not paying for "convenience." You're paying for an extra day per week that you couldn't unlock otherwise.
The capacity ceiling — without hiring
The biggest reason this math matters: you don't need to hire to capture it. No second crew. No second truck. No payroll, no insurance, no onboarding. The +$15K/month is pure operational throughput from the same labor cost.
If you wanted that revenue lift by adding a second crew, you'd need to spend roughly $15K–$20K a month in wages, taxes, insurance, vehicle, and tools — and you'd need enough work in the pipeline to justify it. Most one-crew operations don't have either when they're running mud-bed installs.
Risk math: callbacks and warranty exposure
It's not just revenue. Mortar-bed installs have higher failure points: uneven cure, soft spots, drain-joint leaks. Each callback eats half a day, kills your reputation, and risks a warranty claim. Prefab pre-sloped systems with factory-bonded drains and 10-year manufacturer warranties cut that risk dramatically.
One avoided callback per month at $500 in labor saved (your time + a helper) is another $500/month back. Over a year, that's $6,000 in unrecovered labor cost saved — on top of the revenue lift.
Bottom line
The math is conservative. The Speedy Superkit at $870–$1,067 pays for itself on the first install. After that, every extra job per week is $3,500 of incremental revenue you couldn't have hit on the old workflow — for roughly +$15K/month in added capacity at one crew.
If you're running multiple crews, multiply. If you're solo, the math still works — fewer days per shower means more jobs per quarter, faster cash cycles, and lower stress.
