The Project Overview:

This project in South Langley involved a complete ground-up rough-in for a high-end basement bathroom. Unlike a standard renovation, this required cutting into the existing concrete slab to relocate the main waste lines. For a bathroom to function properly in a basement, the “fall” (slope) of the pipes must be calculated with zero margin for error to ensure reliable drainage for years to come.

The Solution:

We executed a “surgical” rough-in, focusing on code compliance and structural integrity.

• Under-Slab Drainage: We excavated and installed 3-inch and 2-inch PVC waste lines for a toilet, walk-in shower, and vanity. Each connection was bedded in sand to prevent shifting and was double-checked for the perfect $1/4$-inch per foot slope.

• Integrated Venting: We installed a dedicated vent stack that ties back into the home’s main venting system, ensuring that sewer gases are safely exhausted and that the shower doesn’t “gurgle” when the toilet is flushed.

• Shower Base Preparation: We set a precision-leveled drain for a custom tiled shower floor, ensuring the waterproofing membrane would have a perfect seal at the flange.

• Quiet Water Lines: We used high-grade PEX-a piping for the hot and cold supplies, utilizing “bend supports” instead of 90-degree elbows where possible. This reduces turbulence and ensures whisper-quiet water flow behind the walls.
