FyberLok™ Shower Layout Guide
FyberLok™ is a hand-applied waterproofing system that fits your shower’s shape beneath the tile. It covers the shower floor, lower surrounding walls, curb and built-in features, and connects to the drain.
Use these jobsite examples to see how FyberLok™ works with your layout and what to include when choosing a kit.
Curbed showers
In a standard curbed shower, FyberLok™ covers the floor, turns up the lower surrounding walls and wraps over the curb onto the bathroom floor. Any overlaps will bond together creating one solid shell.
Allow for the curb and lower wall coverage when sizing your kit—not just the shower’s length and width.
Curbless showers
FyberLok™ is applied over the final mud pitch and continues through the open entry onto the bathroom floor. This brings the sealed transition past the shower’s threshold (where your glass will be set) and onto the bathroom floor surrounding your shower.
This method of applying the FyberLok system is critical for this style of shower. If you do not follow the guide for this style shower it can result in leaks
Include that bathroom-floor extension when planning your coverage and choosing a kit.
Drain connections
FyberLok™ connects to a standard three-piece clamping drain. Plan the drain arrangement with the shower layout before waterproofing begins.
In a linear-drain setup, FyberLok™ lines the recessed channel and runs beneath the linear-drain assembly to the clamping drain below.
Linear drains vary. Give us a call before ordering so we can review the connection for your project.
Seats, benches, and niches
Seats and benches are part of the waterproofing, not an afterthought. FyberLok™ covers the seat top and front and continues onto the adjoining walls, including the corners where they meet.
Full-width benches, side seats, floating seats and niches add surfaces to cover. Include these features when sizing your kit, even in a small shower.
What can it be applied over?
FyberLok™ can be considered for the following surfaces when they are sound, clean and properly prepared. Preparation and suitability depend on the material and your shower construction.
- Cement/mortar and cured concrete: including the shower’s final mud pitch, with a firm surface free of loose material and contamination.
- Wood and plywood: dry, sound and properly supported, with preparation suited to the project.
- Cement-based backer boards: confirm the specific board and its surface preparation with us before ordering.
- Existing cured fiberglass: assessed and prepared for a reliable bond, including removal of wax and other surface contamination.
For metal, glass, stone or ABS/PVC surfaces, contact us first. These need a material-specific compatibility and preparation review.
Before you choose a kit
FyberLok™ goes over the prepared shower, including the final mud pitch; it does not form the shower’s pitch. Have your layout and drain arrangement planned before ordering.
Size your kit for all the surfaces you will waterproof: the floor, lower walls, curb, seats, niches and any extension onto the bathroom floor. The floor footprint alone does not account for the whole job.
Compare your total coverage with the Standard or Plus kit. If you’re unsure, send us a sketch, measurements and drain details so we can help you choose.
