What are the advantages of your product in comparison to other
manufacturers of wooden washbasins and baths?
Firstly, no one else in the world has the experience in this field
that we have. The main difference to others is the absolutely
perfect paint surface and the annual rings that shimmer uniquely. No
other manufacturer offers a more perfect paint surface and we are
aware of this statement. Most of our competitors produce bathtubs
from solid wood blocks without the use of lacquer. This is of course
very beautiful and close to nature, but such surfaces should be
treated regularly and continuously with oil, preferably every 6
months, during normal use. The blocks are not dimensionally stable
in the long run, as the wood is alive. And when the manufacturers of
these washbasins / bathtubs claim that their product does not
require any treatment, they simply do not tell the whole truth.
The use of varnish gives us ample opportunity to customize the
product according to individual customer needs. You can engrave an
unusual leaf, flower or blade of grass, jewellery, or even a
picture. For example, for a Swiss watchmaker we made a washbasin
with a crack filled with watch gears.
What is the warranty on your wooden products?
We provide a 10 year warranty on all of our products made using our
technology. The warranty is applied to product integrity and the
formation of spontaneous fractures, and does not cover damage caused
by mechanical impact or neglect.
Setting the warranty aside, how long will we be able to use this
washbasin or tub in wood?
In our experience at least 20 years — there are precedents — but
actually probably much longer, as after a decade of use the products
still look brand new.
Do I need to take care of the wooden surface in a special way and
how often? Is there anything to avoid?
Our products do not require special maintenance or care.
Do not use abrasive cleaners (powders and pastes containing solid
Toothpaste, soap and water residue is easy to remove with a wet
towel without using any cleaners.
You should use only anti-calc products or lemon acid to clean
Treat and polish an item surface as if it were your car varnish
coating, and the product will preserve its original beauty and
luster for years to come.
What should I do if the wooden surface is somehow damaged?
In order to damage the surface some heavy or sharp object has to
fall from a height of 30–50 cm. This may fatally damage an ordinary
ceramic washbasin, but a wooden item can be repaired. Depending on
the complexity of damage there are the following options:
If the surface is scratched, any car painting specialist (or even
yourself, with a proper grinding tool) will be able to polish a
scratch. Feel free to use any car polishing devices for our
surfaces. There are companies that offer small repairs of lacquer
surfaces on the site — you can also contact them.
If damage is serous and affects the very core of the wood, there
will not be a crack so any furniture workshop working with
polyester lacquers can assist you.
How does the wooden surface react to conventional cleaning agents?
Perfectly normally. Very important: do not use abrasive cleaners
like powders and pastes containing solid abrasives!
Which wood surface finishes are possible?
The most beautiful surface is our “Grand Piano” high gloss surface,
which allows an incredibly beautiful wood picture depth. In our
times and especially with minimalist designs, a natural satin
surface is in trend. We can do both, whereby the sharpness of the
wood image is somewhat lost in the satin variant. As a compromise,
we recommend our customers to combine furniture with a satin
surface, with washbasins and smaller accent parts in high gloss.

What kind of material is mineral casting?
Mineral casting (cast marble) is a material consisting of mineral
fillers, the main component being marble powder (57-80%), epoxy
binders and pigments. The material is mixed in different proportions
depending on the desired result.
For example, our bathtubs with gelcoat coating contain up to up to
85% marble powder, the bathtubs with a natural surface (white, black
black or concrete) up to 70% and the transparent bathtubs of the
Kaleidoscope series up to 60% of this substance.
The production of bathtubs or washbasins proceeds as follows: the
homogeneous mixture is poured into steel or plastic moulds in a cold
state and then brought to its final state by careful grinding.
Mineral casting has a very smooth surface without pores or seams and
therefore does not allow dirt, bacteria and germs to settle. Cast
mineral bathtubs are very durable, easy to clean, their surface
feels warm and velvety. They also store heat very well.
In direct comparison to ceramics, mineral cast objects are much
softer. Scratches are hardly possible on ceramic. However, if the
ceramic surface is cracked, it cannot be repaired. The mineral cast
surface is hard enough, but in addition to its positive haptic and
optical properties, it has the following advantage: it can almost
always be repaired. The traces of use and minor scratches that can
appear over the years can be easily removed by simply sanding with
special soft pads.
The actual lifespan of cast marble bathtubs and washbasins is 30 to
How can I freshen up my cast mineral bathtub or washbasin?
If you decide to freshen up your precious wood basin or bathtub
(this applies to white material), then the wooden, lacquered edge of
the basin or bathtub must be carefully covered with painter's
masking tape to avoid damage to both the joints between the veneer
and the basin or bathtub and the veneered and lacquered wooden
surface. For sanding, please use the 3M™ Soft Pads: 03810 "Super
Fine", which is usually included with the basin/tub set.
Our mineral cast basins and tubs in concrete and black can also be
sanded, but here it is better to involve a professional.
What is gelcoat?
Gelcoat can be described as a protective layer for the underlying
material, in our case the mineral casting. It protects the surface
from scratches, UV rays and is chemically very resistant. The very
smooth, semi-gloss surface prevents dirt, bacteria and germs from
The reason we use it in the manufacture of baths is that it can be
coloured in any RAL colour. Up to 2,000 shades and colours are
possible, which opens up unlimited possibilities for the customer.
The actual lifespan of gel-coated bathtubs is between 30 and 60
The gelcoat surface itself is very hard and, unlike our mineral
cast bathtubs with a natural surface, does not need to be repaired
or renewed by sanding. In contrast, the surface can be damaged by
Is the procedure of washbasin and bath installation the same as for
conventional washbasins and baths?
Yes, absolutely, since all dimensions conform to international
Can I use any drain plug?
Yes, any, but with a closing tool in the washbasin plug itself and
any standard for the bath. Drain plugs with the engraved washbasin
designer logo are always in the set.
Can I use any water tap?
Actually yes, because there are always different ways to adjust the
strength and direction of the water jet. However, if you have a
mixer with an open spout, it is always better if the spout is placed
relatively close to the washbasin surface.
Where does Ammonitum produce?
The actual product design, planning, project development,
production of the 3D visualizations, interior design take place
mainly in Switzerland, at the headquarters of our company in Zug
and in Lugano.
Production is in Bavaria, Germany, at two production sites in
In Prien near Rosenheim, the purchased wood material is stored,
cut into layers for further processing, dried and glued into
blocks. Afterwards, these blocks are used to produce finished
bathtub and washbasin blanks. Smaller furniture orders are also
carried out in Prien.
In Jetzendorf, the shape and surface are perfected, made ready
for lacquering and then lacquered for a very long and costly
time. Our production plant in Jetzendorf are leaving perfect
objects ready for shipment.
