Custom Shower Pans
Professional custom shower pan installation
Waterproof, Durable, and Perfectly Sloped Showers
The foundation of any high-quality, long-lasting tile shower is the shower pan. At Posch Tile, we specialize in the construction and installation of custom shower pans in San Francisco Bay Area, CA. A poorly built shower pan will inevitably lead to standing water, mold, leaks, and catastrophic water damage to your home. We ensure your shower is built right from the ground up.
Whether you are designing an oversized luxury shower, a curbless walk-in enclosure, or outfitting an oddly shaped bathroom, pre-fabricated fiberglass bases often won't cut it. We hand-build custom, mortar-bed shower pans that are perfectly sloped, 100% waterproof, and ready to be finished with the beautiful tile or natural stone of your choice.

Why You Need a Custom Shower Pan
A custom shower pan offers flexibility, durability, and peace of mind.

Superior Waterproofing: Built using industry-leading waterproof membranes to guarantee zero leaks.
Premium Aesthetic:
Allows you to continue your bathroom floor tile directly into the shower base.
Our Custom Shower Pan Construction Process
Building a shower pan is highly technical. We do not cut corners on plumbing or waterproofing.
Subfloor Preparation & Framing: We evaluate the subfloor for structural integrity and adjust framing as needed, especially for curbless designs.
Pre-Pitch & Liner Installation: We install a perfectly graded pre-pitch mortar bed, followed by a durable waterproof liner that ties directly into the drain assembly.
Final Mortar Bed (Mud Job): We hand-pack a final mortar bed over the liner, perfectly sloping it at the required 1/4-inch per foot toward the drain to ensure fast, complete water runoff.
Waterproofing Membrane: For modern systems (like Schluter or Wedi), we expertly apply topical waterproofing membranes, sealing all seams and corners before tiling begins.
Shower Drain Options
We can customize your pan to accommodate various modern drain styles:
Traditional Center Drains: Classic, efficient, and perfect for smaller mosaic tiles.
Linear Drains: Sleek, modern drains placed at the wall edge, allowing you to use large-format tiles on the shower floor.
Hidden/Tile-In Drains: The drain grate is filled with a piece of matching tile, making it virtually disappear into the floor.

FAQS
Frequently Asked Questions
What is the difference between a custom pan and an acrylic base?
An acrylic base is a pre-made plastic pan that comes in set sizes. A custom pan is built from scratch using mortar and waterproofing, allowing for any size, shape, and the application of custom tile.
Can you build a shower pan with no curb?
Yes! Curbless showers are very popular. They require specific subfloor modifications to ensure the shower floor slopes down to the drain without a step-up.
How long does it take to build a custom shower pan?
The pan construction, waterproofing, and curing process usually takes a couple of days before the tile can be installed.
Do you also do the tile work over the pan?
Absolutely. We build the pan and handle the complete tile installation for a seamless, turnkey shower renovation.
