The Prosaunas Alder Inside Corner Trim brings a clean, furniture-quality finish to your sauna's interior corners. Crafted from alder — prized for its warm reddish tone and pleasant texture — this trim piece ties together your sauna's look with a refined, intentional touch.
Alder has earned its place as a go-to sauna finishing wood. Its naturally appealing texture and distinctive reddish hue make it a popular choice for interior sauna applications, delivering a consistent, attractive appearance throughout your space.
Prosaunas draws on more than 55 years of sauna craftsmanship to select only the finest alder from Northern Europe and Canada. Every piece meets strict quality standards, so you can count on consistent color, grain, and cut — right to your door. Actual dimensions are 14 × 30 mm with a length of 292 mm.







Trim pieces are cut to length and fastened into the interior corners of the sauna as part of the wall finishing stage. You will fit and secure each piece during final interior installation.
This inside corner trim is milled from alder and sized at 1x2 (14mm x 30mm) to cover the interior angles where sauna walls meet. A clean corner finish matters because exposed panel edges can catch moisture and show movement over time — trim locks them in place and gives the interior a deliberate, finished appearance.
Available in eight lengths from 1 foot (292mm) through 8 feet, you can select exactly what each corner run requires and minimize on-site cutting. Ordering to length keeps waste low and ensures the grain profile reads consistently across the full height of the wall.

Sauna wood is not free shipping. Length, piece count, profile, and weight set the rate. These are the Bathing Brands contiguous-US flat rates. Canada is the same table plus $100. Alaska, Hawaii, and remote addresses are quoted.
Checkout charges the 8' piece-count table (contiguous US). Canada is the same table plus $100. Boards over 8' use that same checkout rate; dock or liftgate extras are a follow-up. Alaska, Hawaii, and remote addresses are quoted.
Under 40 pieces generally ships FedEx Ground in cardboard. Over 40 pieces generally ships LTL with a liftgate on a wood pallet. The longest board in the order sets the rate tier.
These lengths ship LTL on a wood pallet. They do not qualify for a liftgate — you need a dock, machinery, or hand offload on site. Carriers allow about one hour to unload before extra fees.

Everything as advertised. Easy set-up and a great addition to our sauna. I had a few questions and received prompt replies and great customer service. I would order again.

Absolutely stellar interaction with Mitch. Cannot thank them enough. Would do business again without a thought in the matter!
Mitch and the team were incredibly thoughtful and patient while I worked on my order. Shipping was clear and conciencias and everything arrived as it should
Communication and attention to customer service was amazing!!!
Love our large sauna! Actually put it together by myself.....was not recommended but can be done! Exactly as advertised! Great service!
This is a great cedar-sided cold plunge tub. I spent a considerable amount of time researching cold plunge tubs and wanted one with real ceder wood to fit my sauna room. It also has a durable heat pump, compared to lower-quality chillers. I have had it a few months and no issues. Also, in the pics below, I have the chiller, which is about a 2' x 2' cube plumbed to a different space for a clean sauna room look. I would highly recommend this tub and the price is less than some on the market.
These guys are AMAZING! I’d leave 10 stars if I could. We purchased a barrel sauna and cold plunge from them in fall 2025. They were absolutely terrific to work with! Our contractor and electrician had many (many) questions, all were promptly and kindly answered. They even customized our order by selling an extra long cord so we could install control panel inside for extra protection in MN winters. Shipping and delivery was a breeze. We are using our sauna daily and love it! Zero hesitation recommending this company! Thank you Johnny and Mitch for all your help!!!

Researched many saunas for many months. Finally landed on this one. Only complaints i have are the instructions weren't very well written and the trim on the outside was very difficult to put together. We use it almost daily.
Super stoked about the new sauna. I ended up with a beautiful 2-3 person cedar sauna with a huum heater. It’s perfect. These guys were helpful in choosing the right size, type, etc.
very glad I used the cold plunge guys.
Received order quickly. Great service
Had a great experience working with the Cold Plunge Guys and would highly recommend their products!
Honest, knowledgeable and reliable. I appreciate all the care that goes into each personal interaction.
I ordered my heater on a Thursday and it arrived the following Tuesday.
The price was by far the lowest I was able to find. I am super impressed with this company.
