slanted ofuro 3D

Is the ofuro free standing?
Or is it built into a ledge?
Since it has a slanted edge, do you see it from outside?

We had problems explaining the image to the client so we resorted to sketchup and everything was easy!

It is drafted quite roughly, but if you want you can download the model below from the sketchup warehouse.
We also have another couple of models in the warehouse. Search with “bartok” as keyword, you should find them.

ofuro for the elderly

Nowadays wooden bathtubs are popular in rehabilitation facilities and retirement homes for the elderly.
Wood is soft and warm and it is very appreciated especially by people with pain or physical limitations.
Here below are two examples. it is easy to mount railings or neck holder fixtures.

Also, it is common to install a movable partition inside to adjust the size. This way it can be used by multiple people as well as singularly.

The worry is that if the tub is too big, elderly people may slip inside the tub and drown.
For this reason it is recommended to use a size so that you can reach the back end of the tub with your feet.

This thinking is recommended in general while it is not really necessary for an adult/fit person.

flooring for Singapore house

We were contacted by an architect renovating his home in Singapore.
The client was keen on hinoki material but did not like the traditional “white-pink melange” look of japanese evergreens.
After considering several options, the client opted for a more expensive “all heartwood” material.
The sapwood is eliminated before sawing and milling the planks so the color is more uniform and the lumber itself is harder.
IMGP9158
We milled a tongue and grove on the long sides but did not manufacture the end matching joint (the planks would have become about 4cm shorter and would not fit the module of the project)
IMGP9155
Also, we were requested not to bevel the edges. Our grumpy carpenter was quite uneasy about this (eliminating the corners make the flooring look more regular and prevents indenting of the edges during installation)
But we agreed that everybody would manipulate and install the planks with the utmost care and were able to manufacture the custom “perfectly flat” product.
IMGP9153
The specs/sizes of the flooring are:
material: hinoki (Yoshino-Nara pref.) all heartwood
size: 2000mm x 150mm x 15mm.

I am looking forward to seeing the completed room!

ofuro for Cape Town -3- manufacture

This is sequel of the manufacture of the tub for South Africa.
for those who missed it check in a separate window part 1part 2

So, the planks have been laminated and the edges trimmed (you can see on the wall a plank before being rectified)

IMG_0068
The tongue and grove joint is hand made with a handsaw and chisel. To see the process and understand the way the japanese ofuro water-tightness is assured, refer to the second video from the top in our media section
IMG_0066
3 faces have been assembled together. Now is time to insert the bottom plank. Finally, the last wall will be hand-planed on both sides before being set in place and close the circle.
IMG_0070
You can see here the geometry of the traditional “Tjoint”
IMG_0071
To tighten up the faces, we use long stainless steel bolts. The head of the bolts is capped with round wooden dowels (for a natural look) or copper plates (the traditional detail of the Edo area, borrowed from the ship building practices).

ofuro for Cape Town -2- start work

Continues from a previous post. Open the blog about “choosing the lumber” in a separate window.

We have been contacted by a private client in South Africa about 3 years ago.
He was going to build a new house overlooking the sea and wanted a japanese bathtub.
Apparently it took more than expected for the permits and to start construction but he got back to us and placed the order. We have a comfortable time frame but since we will ship by ocean freight we started construction:
IMG_0054
First the planks are planed

IMG_0057
Then the material to compose the side walls is selected also considering the grain direction (both to avoid warping and for the aesthetic balance)

IMG_0060
Then thru-holes are opened in the sections of the planks

IMG_0061
and the different parts are composed together with the aid of wood dowels and waterproof glue (only on the matching sections)

IMG_0063
The laminated side walls are pressed and left to rest for few days to dry and stabilize

shipping using DHL, FEDEX, USHIP

IMGP9058

We shipped the round tub to singapore using DHL.
Recently Fedex and DHL are becoming more and more competitive costwise.

Also, we learned from a client a new way to find a competitive shipping company.
See the link below.
http://www.uship.com/ca/shipment/wooden-bathtub-httpbartokdesigncomproduc/657797908/

Basically, if I understand, you put tentatively your infomration and some shippers or other users (a kind of group-on?) contact you if there a good option of the possibility of consolidating the shipping.

Best luck!

ofuro for Cape town -1- lumber choice

IMGP8951Today we prepared the lumber for another tub going to South Africa.

The material is asnaro (also known as hiba) wood.
We are currently working on other units so the lamination and assembly work will actually start at the beginning of september and should take about 2 weeks.

IMGP8954You can see some stains. This is not water but natural oil contained in the wood. This is the source of the aroma!
Also, the fact that the plank is blackish is the proof it is well seasoned and fully dry. Of course once planed it will show its white face. It is a very high quality lumber.

IMGP8956You can see the lumber is quarter sawn (parallel wood grain lines) and Mr. Ikeda is optimizing the cuts to mach as much as possible the bent line of the trunk
IMGP8958the sapwood area close to the bark is reduced as much as possible.
IMGP8963finally, this is material to build one ofuro  1500x750mm.

Tanoshimi ni matte kudasai! (Look forward to see it complete!)

Japanese ridge beam on Washington shore

I would like to publish here a mail I received from a lasdscape designer based in Portland.

Hello Iacopo,

I’ve enjoyed your newsletters and information about your business. I thought I’d share this with you, as I begin to design a small structure using this ridge beam I extracted from the driftwood on the SE Washington shoreline yesterday. I believe it certainly is from 2011 tsunami. I’d like to honor its history and journey by giving it a renewed use, following the lines it dictates.

As I research how

it was used, I wonder if you would have a resource for me to consult that could indicate a likely representation of its position within a structure? I may have it figured out, but a few comments from a carpenter there would be quite meaningful.

Than you for any consideration and dialog.

Best,

Jon Ensign
Portland, Oregon

I am so humbled and grateful! Thanks to this homepage I have the opportunity to get in touch with amazing people who share their passion for handcrafts and for japanese culture.
Life is wonderful! 😉

For the curious, here below is my answer:

hinoki flooring for indonesia

This time we shipped a large quantity of hinoki flooring to indonesia.
IMGP9107
The planks have a end match joint.

IMGP9105

We also shipped waterproofing treatment to be applied after installation.
One large can of “kihada ichiban” contains 16Kg and can cover 100m2.
The cost is 100,000JPY + packaging + shipping.
We also can sell 1L, 4L bins.

IMGP9104

Specs for the project:
– Hinoki flooring-
Origin: Kumano (Mie Pref.)
Quality: one face knotless
Cut: ITAME (plank cut)
Finish: planer finish, no coating, tongue/groove edge, end match
Sizes: W120mm x t 12mm x L 2950mm:

hinoki flooring for your projects!

Maybe not all of you know that we can also supply hinoki wood for flooring or wainscoting?
For interior products (wood not used in wet areas) we use trees from man planted forests (Mainly Kumano area in Mie prefecture and Yoshino area in Nara prefecture.)
IMGP7011

They are very regular and have few knots so we can obtain high quality solid flooring for a reasonable price.
The peculiarity of the material is a mix of “shirata”(sapwood=white) and “akami”(heartwood=red) areas.
The lumber is cut parallel to one direction (plank cut) so the planks are mixed by nature.

IMGP8967

Some people like this look, peculiar of sugi pine and japanese hinoki.
Anyway, if you prefer a more uniform look, the only way to obtain material of the same color is to cut away the sap wood and use only the core of each trunk. This brings up the cost by about 50%.

IMGP8968

Hinoki flooring is used without shoes and is normally un-coated. It is possible to coat it with urethane but this would interfere with two of the nice features of hinoki flooring: the subtle cedar aroma and the soft/warm touch. To make the upkeep easier, we recommend the application of a full penetration water repellent (Kihada ichiban). The product is applied after installation of the flooring so we will supply separately the cans and you will apply on site with a wide brush in 2 coats.

IMGP8972

All the flooring is manufactured as per your order so you can choose the thickness (usually 12, 15 or 18mm), the width (90, 105, 120, 150, 180mm or custom) and length of the planks(2m,3m,4m or custom), the quality and type of processing (tongue/groove, end matching joints, mitered joints, width of bevel etc.)

IMGP8980

plank with tongue and groove + end matching joint

IMGP8981

Here is a reference of sizes/prices in case of 12mm thick material.
The prices are for a minimum quantity of 50m2 or more.

Origin: Kumano (Mie Pref.)
Quality: surface knotless
Cut: ITAME (plank cut)
Finish: planer finish, no coating, tongue/groove edge, end match
thickness: 12mm
w120 x L 1950: @3,020 JPY per piece
w120 x L 2950: @3,950 JPY per piece
w120 x L 3950: @7,000 JPY per piece

w150 x L 1950: @4,000 JPY per piece
w150 x L 2950: @5,900 JPY per piece
w150 x L 3950: @9,200 JPY per piece

The best cost/performance for a 12mm flooring is obtained by using the 3m planks.

For installation use both glue and nails following the procedure as per the sketch here below.
flooring01flooring02

Hammer the nails diagonally and make them flush with the aid of a punch before laying down the next plank. Proceed until you reach the other end. It is recommended to tuck in the planks with the aid of a hammer to make sure there is no gap between the joints.

NOTE: Solid hinoki flooring is not compatible with floor heating.
