Everything the assembly needs — from substrate to sealant
Four focused product lines built for waterproofing and tile installation. Spec a full wet-area assembly without juggling five suppliers.
Underlayment
Waterproofing membranes and uncoupling mats that isolate movement and stop water at the substrate — the difference between a job that lasts and a callback.
View membranesShower Kit
Tile-ready, fully sealed shower pans, curbs, and prefab or custom niches. Sized to your opening so the crew sets tile, not problems.
View shower kitsTools & Sundries
Trowels, leveling clips and wedges, spacers, adhesives, performance sealant — the consumables that keep a crew moving, stocked by the case.

Installation speed, code-credible assemblies, terms that respect trade work
Wet-area performance
Bonded waterproofing and uncoupling that meets the code your inspector reads. Every wet-area component is spec'd to work as one assembly — no mystery layers, no guesswork.
Reliable stock
We carry depth on the materials you reorder most, so a Tuesday membrane shortage doesn't stall a Thursday pour. Predictable inventory, no back-order surprises.
Trade economics
Wholesale pricing built for trade volume — terms that protect your margins, not retail packaging or showroom markup. The more you build, the better it works.

Foam backer board vs. cement backer board
Both have a place on the truck. Here's the honest, side-by-side so you can spec the right substrate for the assembly — and the schedule.
| Property | StreamlineEssenti foam board | Cement backer board |
|---|---|---|
| Built-in waterproofing | Integral moisture barrier | Needs separate membrane |
| Board weight (per sheet) | Lightweight — a one-person carry | Heavy — typically a two-person lift |
| Cutting & handling | Score-and-snap with a utility knife | Carbide blade, silica dust, scoring tools |
| Mold & rot resistance | No organic food source | Resistant, but joints still need treatment |
| Install speed | Faster — fewer layers, lighter handling | Slower — membrane is a separate step |
| Best fit | Showers, steam, wet floors, fast turnarounds | Floors, countertops, high-impact dry areas |
Need both on the same job? We stock cementitious backer too — talk to us about a mixed pallet.

Q&A
Answers to common questions
Do I need a trade account to buy from you?
We're a B2B wholesale supplier built around licensed contractors, builders, and distributors. Trade accounts unlock our best pricing and terms — but serious DIY remodelers are welcome to request a quote on any material. Either way, pricing is account-gated, so start with a quote request.
What area do you deliver to?
We stock and ship from Portland and deliver across the Pacific Northwest, with a standard 24–48 hour window on local orders. Will-call pickup is available at our PDX location. Larger or recurring jobs can be scheduled on a standing delivery cadence.
Is Essenti foam board really code-compliant for showers?
Yes. Essenti Board carries an integral moisture barrier and is engineered for code-aligned wet-area assemblies when installed per spec — bonded seams, sealed fasteners, and corners treated. We'll provide submittal documentation on request so your assembly clears inspection.
Can you size shower pans and niches to my opening?
Absolutely. We stock common sizes for fast turnarounds and build custom pans, curbs, and niches to your rough opening. Send dimensions with your quote request and we'll confirm lead time — most custom pieces ship inside the same week.
