Custom tubs

japanese room for italian hotel (3)

We also supplied other construction materials for a tatami room in the spa which is mainly going to be used for massage therapy.

This is the “naguribori” floor have you ever seen it? It creates a great atmosphere and is also very pleasant to step on with bare feet. The design comes from the ancient technique of roughing out wood planks using a mattok like tool to make the planks flat and even.


If needed the floor was then smoothed out with a had plane. But of course in this case we chose it  for its texture.

The planks are already processed with a tongue and groove matching joint for easy assembly.


We also supplied tatami finished with natural “igusa” straw. Enjoy the sweet aroma of tatami and their slow discoloration from green to light tobacco color. The inside of the tatami is not the traditional thickly packed straw but rather a sandwich of plywood and styrofoam. This is not the most authentic tatami construction but is now used in 95% of tatami rooms in Japan, including temples and heritage buildings. It does not sag overtime and prevents the insurgence of mold and insects.


Here is a layout of the tatami room. There is a “correct way” for any layout, so please consult with us by providing the internal dimensions of the room (width x depth) we will make the calculations as the best size for the individual mats.

and here is a selection of the edge fabric (eri). If it was you which color would you have picked up?


Finally, we also supplied the fabric to finish the closet doors. We can also supply the finished “fusuma” doors, but in this case the client decided that they would have more flexibility to make the doors on site. I also provided some recessed handles so they can pickup the design that best matches the other elements of the room. Once the doors are coated with the silk fabric I am sure you will feel like you are in a luxurious ryokan in Kyoto!

Of course I will provide support thru email/skype for a proper choice of materials and detailing.


ofuro for italian hotel (2)

This is the second tub used in the new “fusion spa” of the  PALAZZO DI VARIGNANA RESORT & SPA near Bologna (Italy)


It is rightfully labeled “Onsen grande” (large onsen) and rivals in size with the basins used in japanese hot springs.

Here are the specs:

material: knotless asnaro wood from aomori prefecture

size: 1800x1800x H650 mm / top frame border
option: 2 asnaro wood internal seat (fixed) W400mm
This tub can comfortably sit 4 strangers or 6 friends/family members.


“Panorama view” of the large internal seat. The planks would be too long and unstable if they were removable so we decided to make them fixed.


The space between the 2 benches. When used only by one or 2 guests, it is possible to sit lengthwise in the deep area.


accessories include an Asnaro wood floor mounted spout with internal faucet


This is the full picture of the spout with other accessories such as hinoki wood traditional stool (300x180x200H) and Sawara wood ladles with handle (te-oke).


ofuro for italian hotel (1)

We received an order of 2 large ofuros + accessories and construction material (flooring, tatami, shoji doors) for a spa corner inside a large villa converted in Hotel near Bologna (Italy).

A friend running a spa-equipment company (YOU SPA) kindly referred us to the client.

He made the concept design for the spa area with a modern touch. I am looking forward to the pictures of the completed space!


This is what they call “Onsen piccolo” (small … bathtub).

It is a statuary hinoki bathtub which can fit about two sumo wrestlers!

Here below are the specs:


material: knotless hinoki from the Kiso Valley (Nagano prefecture), quarter sawn

sizes: 1800x1000x H650 mm with top frame border

option:  2 Hinoki wood internal seat (removable) W400mm


The drain is tucked in a corner.


The tub will be also equipped with a wall mounted hinoki spout (see photo below)


My partner Ikeda-san is very proud of this tub and could not help posing by his new masterpiece. I said “SMILE!” but this was the maximum I could obtain from him… We have been working together 14 years now, but he is unchanged: born in the Kiso valley like all the hinoki we use, our hinoki expert Ikeda-san is made out of stainless steel!


asnaro doubleseater for Odessa

This is the first Bartok design tub going to Ukraine.

The client had problems in contacting us and for some reason the e-mails were bouncing off from the server. But she used an alternative email and we could define the details in few rounds.


Here are the specs of the tub:

material: natural Japanese Asnaro AB (quarter sawn)

sizes: L1400mm x W800 x H685mm (ext. dim.)

details: nat. oil apron,  wood dowels. Iron brand at front side top-right.

The tub was shipped thru a forwarder appointed by the client. We arranged for the pickup directly from our packing company which is already very close to Narita airport.


It is a perfect tub for 2 people. I hope the clients can have relaxing chats and enjoy the fresh aroma of japanese wood it for many years to come! Of course the seats can be quickly removed for a deep plunge japanese style soaking experience.


asnaro tub for Dallas

Compact and cute asnaro bathtub ordered thru an architectural office in Texas.
From the first request of information to shipping it took 1 month exactly so I can say it was a smooth order process.
The client is going to use it in a master bathroom remodel and after the initial quotation, we modified the corner joints from metal plates to wooden dowels and added an overflow cut on the short side.

Here below are the specs of the tub:

material: natural Japanese Asnaro AB grade bathtub (quarter sawn)
sizes: L900mm x W700 x H710mm (ext. dim.)

cold plunge hinoki tub

As the title says, this tub will be used for a cold water plunge so it does not have an internal seat.

The tub was ordered thru a very collabotarive architecture office and we had a positive and efficient exchange of information back and forth.
This is something we have to thank the technology for…
On the other hand, the tub itself is 100% analogic.
Even though for box type tubs we can build precisely (tolerance of +/-1mm) a round tub of this size may have a tolerance of +/-10mm!

There is a saying that round tubs do not close if they are built by calculation.
A round tub is beautiful (and functional) only if it is built with the heart!

Here below are the specs of the tub:

material: natural Japanese Hinoki cypress AB grade bathtub (quartersawn)
sizes: Dia 1220mm x H958mm (external dimensions) 838mm(deep)
details: stainless steel bands
– Hinoki wood step stool W500mm x D400mm x H400mm
– Complimentary hygrometer


We made a similar tub for a californian client in 2009.
His mother apparently likes the tub too so we received another order: same shape, same size, same material.

There is one problem though: the double slanted tub we made in 2009 was a hit. It was published on an american interior design magazine and was featured in a japanese TV program.
The wood knots pattern -unpredictable by nature- was very well balanced: powerful and refined at the same time.

The problem is this: can we make a tub with a knot pattern that is at least as nice as the son’s?
We do not want to be the cause of family jealousy…

But yes: the miracle happened twice! The tub is as beautiful (if not even more) as the 2009 one: compare yourself.
