assembling and joining

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.
