Karlovy Vary Spa Drinking Cup: History, Spout & How to Choose
The Karlovy Vary Spa Drinking Cup: History, Why the Spout and How to Choose Yours
Author: Feel Karlovy Vary editorial team
If you've been to Karlovy Vary or seen photographs from the resort, you've almost certainly noticed it: people walking the colonnades carrying small porcelain cups with a long spout. Not ordinary mugs and not glasses — something between a teacup and a miniature teapot.
This is the Karlovy Vary spa drinking cup. And it has a story worth knowing — especially if you're planning a visit, or if you've already brought one home and found yourself wondering: what exactly is that spout for?
A Brief History: From Clay Bowl to Porcelain Symbol
The 16th Century: the Birth of Drinking Therapy
The history of the spa cup begins not with the cup itself but with an idea. In the 16th century, the Karlovy Vary physician Václav Payer made what was, for its time, a revolutionary proposal: the mineral water of the Karlovy Vary springs should not only be used for bathing but also for drinking. This was the beginning of drinking therapy — a treatment method still practised in Karlovy Vary to this day.
Patients rushed to drink. But drinking hot mineral water is no trivial task. In the early period, whatever came to hand was used: clay bowls, tin cups, glass vessels. The history of the spa cup as a defined object begins in the 17th century.
The 17th–18th Centuries: the Search for a Form
Over two centuries, the shape of the cup evolved. Patients experimented with materials: glass, tin, clay and later — porcelain, which became available in the 18th century thanks to the development of Bohemian porcelain production. North-western Bohemia — the region around Karlovy Vary and Mariánské Lázně — has rich deposits of kaolin, the key material for porcelain. This region produced one of the strongest European porcelain traditions.
Porcelain proved ideal for the spa cup: it imparts no foreign taste to the water, withstands the high temperatures of the springs, holds its shape well and takes decoration beautifully.
The 19th Century: the Arrival of the Spout
The defining invention — the siphon spout — appeared in the 19th century. A small tube emerging from the lower part of the cup solved two problems at once.
First: cooling the water. Hot mineral water (up to 72°C at some springs) passed through the long spout and cooled slightly on the way to the lips. This allowed patients to drink directly at the spring without waiting for the water to cool.
Second: safety while walking. Drinking therapy in Karlovy Vary is not simply "drink some water and sit down." It is a drinking promenade: the patient walks the colonnades and drinks simultaneously. The spout allowed the cup to be held to the side rather than directly in front of the face, giving a clear view of the path ahead. With an ordinary glass, this would have been considerably more difficult on the uneven surfaces of the colonnades.
After 1900: Flat Cups and Designer Editions
After 1900, flat spa cups came into fashion. The elegant, compact design made them easier to carry — the cup fitted into a coat pocket. Later, designers began creating more elaborate versions, transforming the cup into an art object.
One of the most celebrated examples is the "Calla" cup, designed by Štěpán Kuklík specifically for the Karlovy Vary resort. The name refers to the calla lily: the spout emerges from inside the cup like the pistil of a flower, while gold patterns echo the stems and leaves.
Why the Spout: the Full Explanation
So — why the spout? The answer is several things at once.
Medical function. The correct technique for drinking therapy requires slow drinking in small sips. A wide-mouthed cup or glass encourages large gulps. The narrow spout physically slows the rate of drinking. This is not a quirk of design — it is a deliberate medical decision built into the object.
Temperature function. Mineral water at some Karlovy Vary springs reaches 72°C. The spout cools the water by increasing its contact surface with air as it travels from cup to mouth. By the time it reaches the lips, the water is several degrees cooler than when it was drawn.
Practical function. Drinking while walking on the uneven flagstones of the colonnades with an ordinary glass is awkward. The spout allows the cup to be held away from the face, maintaining a clear view of the path ahead while drinking.
How to Choose a Spa Cup
Choosing a spa cup is a personal matter. But a few parameters are worth considering.
Material
Porcelain — the classic choice. No added taste, hygienic, takes decoration beautifully. Traditional Karlovy Vary cups are made from porcelain. The main drawback is fragility on impact.
Ceramics — more robust than porcelain, usually heavier. Less common for finely decorated versions.
Volume
The standard volume of a spa drinking cup is around 200 ml. This is precisely the volume prescribed by balneologists for a single drink at a spring. Not by chance: the recommended single dose of mineral water at the Karlovy Vary springs is calibrated to this amount. When buying a cup, check the volume — it should be close to 200 ml.
Design
Traditional designs on Karlovy Vary cups feature floral motifs (roses, forget-me-nots, cornflowers), views of the colonnades and city landscapes, often with a gold rim. This is not mere decoration — it is the visual language of Bohemian porcelain with nearly three centuries of history.
Cups come in three varieties:
- Hand-painted — more expensive, each one unique, the brushwork visible
- Decal (transfer print) — a standard pattern reproduced precisely, more affordable
- Personalised — made to order with a name or inscription
The Spout: Shape Matters
The length and angle of the spout affect ease of use. The classic spout emerges from the lower part of the cup at a slight downward angle. Flat cups have a spout emerging from the base or side in a horizontal plane.
For actual use during a drinking cure — the classic vertical spout is more practical. Flat cups tend to serve more as collectors' or decorative items.
The Spa Cup and Karlovy Vary Salt: One and the Same
The spa cup is not just a souvenir. It has a specific practical use if you continue drinking therapy at home with Karlovy Vary drinking salt.
The method is identical to what happens at the springs: dissolve a portion of salt in 200 ml of warm water, pour it into the cup and drink slowly through the spout in small sips over 5–7 minutes. The spout physically slows the drinking — not as a ritual element but as a medical requirement for the correct absorption of minerals through the mucosa.
People who bring a cup home from Karlovy Vary and use it with the salt are reproducing the resort's drinking therapy in the same form it has been practised for centuries. At that point it is no longer a decorative object on a shelf.

FAQ
Why does the Karlovy Vary spa cup have a spout? The spout serves three functions: it cools the hot spring water as it passes through the tube, it slows the rate of drinking (which is important for effective drinking therapy), and it allows drinking while walking along the colonnades without losing sight of the path ahead.
What is a Karlovy Vary spa cup made from? Traditionally from porcelain — a material that imparts no foreign taste to the water, is hygienic and takes decoration well. North-western Bohemia has been one of the leading porcelain-producing regions in Europe since the 17th century.
What volume should a Karlovy Vary spa cup be? The standard volume is around 200 ml. This is the standard single dose of mineral water recommended at the springs by balneologists.
Can the spa cup be used at home? Yes — for a home drinking cure with Karlovy Vary salt. Dissolve a portion of salt in 200 ml of warm water and drink through the spout slowly. This reproduces the correct drinking therapy technique used at the resort.
What is the difference between hand-painted and decal decoration? Hand-painted: each cup is unique, brushwork is visible, more expensive. Decal (transfer print): a standard pattern reproduced precisely, more affordable. For practical use there is no functional difference — for collecting, hand-painted is preferable.
How do I identify an authentic Karlovy Vary spa cup versus a generic souvenir? An authentic spa cup has a spout-tube, a volume of around 200 ml and a manufacturer's mark on the base. The porcelain should be thin and translucent when held to light. The decoration shows traditional Bohemian motifs or Karlovy Vary views.
