manufacture of wooden hot tubs made in japan as per your custom order specifications

hinoki bath-tubs are entirely hand planed ->

1 - SELECTION
The hinoki wood boards are chosen one by one according to the necessity and planned use

2 - PREPARATION
The wood is cut as per the required sizes, eliminating soft areas (young layers) and knots, respecting the direction of the grain.

3 - CALIBRATION
The wood is planed to remove the imperfections and bring it to a uniform thickness.

4 - CUT
With a technique borrowed from boat construction, two planks are partially overlapped and hand sawn: so the adjacent boards are originated by a single cut and can match perfectly.

5 - SASHIKOMI
Wood plugs are used to compose the top border (kamachi) with the 2 lower sections of one side.

6 - TSUNAGI
Rectangular (or round) holes with a stiching pattern are hand-cut on the head of the long sides with the aid of a chisel.

7 - SLITS
Tongue and groove joints are prepared on the heads to ensure solidity and to create a definitive barrier to water leaks.

8 - ASSEMBLING
The 4 sides and the bottom are assembled. We use stainless screws to reinforce the baht-tub while keeping them invisible.

9 - FINISHING
The inside and outside of the bath-tub is planed by hand to obtain a silky smooth surface.We do not need sealants or any chemical product.

10 - FITTINGS
We attach accessories, the drain fitting if requested and apply our iron brand. Please look in the details section for how to personalize your tub. At this stage we also take pictures of the tub and send to you by e-mail for your review and approval.

11 - WRAPPING
The bathtub is protected with airproof wrapping: this is important to preserve the natural humidity of wood during shipment.

12 - SHIPMENT
The hinoki tub and accessories are prepared for shipment in custom built sturdy non-coniferous wood boxes. We arrange the shipment (air or sea-freight) according to your preference and size of box.
