A Polished Finish for Every Corner

Bring furniture-quality refinement to your sauna with the Prosaunas Thermo-Aspen Inside Corner Trim. Sized at 14 × 30 mm and cut to 292 mm, this trim piece tucks neatly into inside corners, turning raw edges into clean, intentional details that elevate the entire room.

Thermo-Aspen: Built for the Heat

Thermally modified Aspen is transformed through an organic process of heat, steam, and pressure — emerging more dimensionally stable, more water-resistant, and far superior to untreated wood for resisting decay, pests, and harmful fungi. It won't secrete resin, splinter, or overheat, making it a natural choice for sauna environments. Its warm, golden-brown tone adds a rich, inviting character to any finish.

Sourced and Crafted to a Higher Standard

Prosaunas selects only the finest wood from Northern Europe and Canada, backed by more than 55 years of experience crafting premium sauna rooms across North America. Every piece meets their stringent quality standards, so you can order with confidence knowing your trim will arrive ready to impress.

Description

This inside corner trim is milled from thermo-aspen, a heat-treated wood that has had its natural sugars and resins drawn out through a high-temperature kiln process. That treatment stabilizes the wood against the repeated moisture and heat cycles inside a sauna, reducing the warping and cracking that untreated softwoods are prone to over time.

At 14 mm × 30 mm, the 1×2 profile is sized to cover the raw edges where two wall panels or a wall and ceiling panel meet at an interior corner, giving the finished surface a clean, intentional appearance. Available in 1-foot and 8-foot lengths to suit both small patch work and full-run installations.

Key Features

Thermo-aspen construction — heat treatment removes resins that can seep out under sauna temperatures, keeping the surface clean and splinter-free over time.
14 mm × 30 mm (1×2) profile — low-profile enough to sit flush at inside corners without intruding into the bench or floor space.
Inside corner application — conceals raw panel edges at wall-to-wall and wall-to-ceiling junctions for a finished look throughout the interior.
Two length options — 1 ft (292 mm) for targeted repairs or short runs, 8 ft for full corner coverage without mid-run seams.

1'

292 mm length — suited to short corner sections, accent details, or patching a single damaged piece.

8'

8-foot length — spans a full floor-to-ceiling corner in most residential saunas, minimizing visible joints.

SHIPPING & DELIVERY

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.

BOARDS UP TO 8'

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.

Under 19 boards — $195
20–39 boards — $395
40–99 boards — $495
100–299 boards — $695
300–499 boards — $895
500–799 boards — $995
800–999 boards — $1,295

BOARDS OVER 8' UP TO 10'

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.

Under 19 boards — $295
20–39 boards — $495
40–99 boards — $595
100–299 boards — $795
300–499 boards — $995

800–999 boards — $1,395

HOW THIS SHIPS

We pack for a safe arrival at the lowest rate that fits the order.
Boards over 8' carry a surcharge because long crates cost more to move than a standard skid.
Heaters, doors, or accessories on the same order can offset some of that freight.

Great Cold Plunge Tub

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!

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!!!

Harvia Cilindro Half Series 6kW Sauna Heater

What a wonderful sauna!

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.

Great service, great sauna

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.
