Use the calculator to build your cut list, then click Reserve Now — Send Cut List. That opens an email pre-filled with your dimensions, cut list, and totals. Add your name and shipping address, hit send, and we'll reply within one business day with a firm price, LTL freight shipping quote to your zip code, and ETA. You approve the quote before we invoice — no surprise charges.

Cedar T&G ships as long lumber on LTL freight, and rates vary widely by destination, dock accessibility, and quantity. Bundling worst-case freight into every order would penalize customers near our Pacific Northwest mill. Instead, we quote actual shipping to your address — usually within one business day of your reservation — so you get the most competitive freight cost possible.

Both are excellent sauna woods with different strengths. Japanese cedar (hinoki-adjacent) offers a lighter color and more subtle aroma; Western Red Cedar delivers deeper color, stronger natural oils, and Pacific Northwest supply-chain shorter lead times. For a full breakdown of aroma, density, oil content, cost, and best-fit builds, read Japanese Cedar vs. Western Red Cedar.

Both are traditional. Horizontal cedar is the most common orientation for compact indoor saunas — it makes rooms feel wider and allows longer continuous board runs. Vertical cedar sheds condensation better and is preferred for outdoor saunas, barrel saunas, and high-use commercial builds. Our calculator lets you set each surface independently so you can price both approaches side by side.

Yes. Standard wall framing has vertical studs at 16" or 24" on center. If you run cedar horizontal, each board crosses the studs and you nail directly to solid framing — no prep needed. If you run cedar vertical, the T&G runs parallel to the studs and has nothing to nail into between the top and bottom plates, so you'll need to add horizontal blocking (2×4 nailers) between the studs every 24" of wall height before installing the cedar. Plan an extra half-day of framing prep per wall if you're going vertical. Add the blocking during rough framing — it's much easier than retrofitting later.

Every board length is rounded UP to the nearest whole foot because we don't cut to inches. The calculator also rounds up the number of runs (rows of boards at the 3" reveal) to make sure your surface is fully covered. The waste factor then adds a further buffer for miters, cutouts around benches and doors, and finger-jointing on long walls. 10% is the standard sauna interior recommendation.

Standard mill lengths are 4', 6', 8', 10', and 12'. The calculator groups your runs into those lengths automatically. For custom lengths (longer than 12', or a specific mix you need), email info@nwimmersion.com with your cut list before reserving.

No — and you shouldn't. In a sauna, cedar should stay bare. Stains, sealants, and finishes off-gas at high temperatures and can leave a chemical smell in the interior. Cedar's own natural oils are all the protection it needs. For cleaning and long-term maintenance, see our cedar sauna cleaning and maintenance guide.

Yes. For orders over 2,000 linear feet or ongoing contractor accounts, email info@nwimmersion.com with your project details and we will review. NW Immersion works with custom sauna builders, spa contractors, and architects across the US.

We ship LTL freight across the continental US as a standard. For Alaska, Hawaii, Canada, and international shipping, email info@nwimmersion.com with your address and cut list. We'll build a custom freight quote — international lumber shipping usually requires phytosanitary certification, which we can arrange.
