Every year, thousands of bathroom renovations fail inspection because of two things: venting mistakes and waterproofing failures. Both are completely preventable — if you know what the code actually says.

The Problem

Most contractors and remodelers learn venting and waterproofing through trial and error — YouTube videos, supply house conversations, and whatever the last inspector told them. The result? Inconsistent knowledge, failed inspections, expensive callbacks, and lost credibility.

The Solution

Bathroom Code Mastery is a structured course that covers:

• ✅ DWV system fundamentals — pipe sizing, slope, materials, and fixture units

• ✅ Every vent type — individual, common, circuit, wet vents, and AAVs

• ✅ Trap arm distances — the exact table and how to measure correctly

• ✅ Waterproofing methods — traditional liners, liquid membranes, sheet membranes

• ✅ Substrate prep — cement board installation, joint treatment, framing requirements

• ✅ Shower assemblies — curb construction, drain types, weep holes

• ✅ Flood testing — how to do it, what passes, and what to do when it fails

• ✅ Inspection prep — complete checklists for rough-in, waterproofing, and final

This isn't theory. It's the exact code knowledge you need to walk onto a jobsite, build it right, and pass inspection without callbacks.
