The new favorite in luxury home decoration! "Household ovens and steam rooms" waterproof and moisture-proof construction methods, water and electricity special circuit capacity and double-North market

The top enjoyment of home health care: dry sauna vs. wet steam

In the greater Taipei area, many homeowners will consider adding a "household oven (Sauna, dry steam)" or a "home steam room (wet steam)" when planning bathroom renovations for villas, penthouses, or luxury homes (such as large villas in Yangmingshan, Tianmu, Linkou, etc.). In order to pursue the ultimate sense of home relaxation. These two devices are very popular in high-end residences at home and abroad. However, because they have completely different physical properties in terms of "temperature" and "humidity", they have extremely high engineering requirements in terms of water and electricity configuration, ventilation and moisture-proofing, and mud work methods. Improper construction will not only cause mold and wood rot throughout the house, but may also cause a fire due to overloading of electricity.

Dry steaming oven construction method: moisture-proof wood and temperature-sensitive configuration

The so-called "dry steaming (sauna)" uses an electric stove to heat volcanic stones to produce high-temperature dry air of up to 70°C to 100°C in a closed wooden room, with humidity usually less than 15%.
1. Selection of Canadian red cedar and hemlock: The walls and benches of the dry steam room must be made of special wood that is moisture-proof, high-temperature resistant and not prone to cracking due to thermal expansion and contraction. Canadian Red Cedar is a golden building material for dry steam rooms because it contains natural antiseptic oils, emits a unique aroma, and has low thermal conductivity (the human body will not be burned when sitting on it).
2. Double-layer thermal insulation material structure: The back of the wooden wall must be filled with high-density rockwool or fiberglass wool as the thermal insulation layer, and a layer of moisture-proof aluminum foil must be laid to block heat loss and prevent high temperature from damaging the external wooden wall.

Wet steam room construction method: vaulted ceiling and strict waterproofing

Compared with dry steaming, the "wet steam room" with a temperature of about 40°C - 50°C but a humidity as high as 100% is several times more difficult to waterproof:
1. Ceiling slope or arch design (key to preventing cold water droplets): The steam chamber is filled with large amounts of hot steam, which condenses into water droplets when it hits the ceiling. If the ceiling is made flat, cold water droplets will randomly fall on the head of the bather, extremely ruining the experience. The correct construction method is to design the ceiling into a "slope" or "arc arch" to allow condensed water droplets to quietly flow down the wall.
2. Heavy waterproofing layer: Walls and floors cannot be made of wood and must be tiled with marble, glass or mosaic tiles. Before laying tiles, the cement wall must be painted with at least three layers of high-efficiency waterproof paint (such as two-component elastic cement or PU waterproof material) to ensure that hot and humid moisture cannot penetrate into the structural wall. Otherwise, within a few months, large areas of mold and wall cancer will develop in adjacent rooms.

Electricity shortcomings: limitations of high-power equipment on dedicated water and electricity circuits

Whether it is an electric furnace for dry steaming ovens or a steam generator for wet steaming, the heating wattage is extremely large, usually above 4.5 kW to 9.0 kW, and the operating voltage must be 220V. During water and electricity construction, general sockets must not be connected at will. An independent "Dedicated Circuit" must be pulled from the distribution box:
Specification 1, 4.5 kW to 6.0 kW equipment:Operating current is approximately 20A to 27A. Must be equipped with and use conductors with a cross-sectional area of ​​at least , and it is mandatory to install a high-sensitivity earth leakage circuit breaker.
Specification 2, 7.5 kW to 9.0 kW equipment: Operating current up to 34A to 41A. This is close to the power limit of ordinary homes. Must be equippedand use size minimum(stranded wire). If the amperage of the main electric meter in an old house is not enough (for example, it is only 50A), when you take a hot bath or turn on the oven, as long as the air conditioner is turned on at the same time, the main meter will directly trip. Therefore, before installation, you must ask a plumber to apply to Taipower to increase the total power capacity to 75A or 100A.

The price of home sauna and steam room construction

In the greater Taipei area, the cost of building such private spa facilities is estimated as follows:
* The equipment can be bought and plugged in, the price is about NT$ 45,000 to NT$ 95,000, and the circuit requirements are low (mostly 110V/15A).
* Including host electric furnace, special woodwork, thermal insulation materials and special 220V/30A circuit. The price of double-north joint belt materials is approximately between NT$ 150,000 and NT$ 280,000.
* Overall costs typically fall above NT$ 180,000 to NT$ 350,000.
Among them, the circuit fee for rewiring the main distribution box and pulling a 14mm² large wire to the bathroom, depending on the length of the wire, will cost approximately NT$ 8,000 to NT$ 18,000.

Commercial acquisitions and businessmen’s luxury property value-adding techniques: the premium secret of spa configuration

For commercial real estate businessmen who focus on the resale of luxury homes or high-end residential renovations, When a buyer inspects a house, seeing a private steam room or red cedar oven in the master bathroom that is comparable to a top club house will greatly enhance the "sense of dignity" and "scarcity" of the item, and can easily createa luxury property. However, when purchasing such items equipped with spa facilities, merchants must ask their own inspection technicians to confirm whether a 14mm² wire diameter and an independent leakage circuit breaker are actually used in the switch box, and to check whether there are traces of wall cancer on adjacent walls. Preventing structural damage caused by waterproofing failure is the golden rule to ensure that high-end property investment profits are not compromised.
