Zone 3 is anywhere outside zones 0, 1, and 2 (subject to specific limits) and where no water jet is likely to be used. No IP rating is required. However, if there is a likelihood of water jets being used for cleaning purposes in zones 1, 2 and 3, a fitting rated a minimum IP65 must be used.
Zone 2. Zone 2 is the area stretching to 600mm outside of the bath or shower, be that above or to the sides of each. This is typically the area that is least likely to get wet but there is a possibility for it to be splashed.
Zone 2 for a bathroom is the same height as zone 1 (2.25m) extended to 0.6m around the bath. The extent of the zones in a bath or shower room can be limited by floors, ceilings and walls. For more detailed information see BS 7671 diagrams 701.1 & 701.2.
The first digit indicates the level of protection from solids, so you can ignore the first digit when looking for bathroom lights. It is the second digit you want to pay attention to, as this indicates how water resistant the light is.
There are 3-bathroom zones that have been identified by the 18th edition IET wiring regulations and all applicable British standards : Zone 0 – Is defined as any area in a bathroom that can hold water. So, any area inside the bath, basin or shower tray.
A full bathroom is made up of four parts: a sink, a shower, a bathtub, and a toilet. Anything less than that, and you can't officially consider it a full bath. Therefore, a bathroom with a sink, toilet, and shower is considered a three-quarter bath. A bathroom with just a sink and a toilet is a half-bath.
A full bathroom features four key elements: a toilet, sink, shower, and bathtub. A 3/4 bathroom has three of those four elements, including a toilet, a sink, and either a shower or bathtub.
Zone 3 (outside zones): Anything outside Zones 0,1 or 2 (subject to specific limits) and where no water jet is likely to be used for cleaning purposes. No specific IP rating is required.
Zone 1 is the area above the bath or shower to a height of 2.25m from the floor. In this zone, a minimum rating of IP45 is required but it is generally accepted that IP65 is to be used. It's also worth noting that most shower lights are rated at IP65 as standard.
Wet rooms must apply to Zone 0.
The most common values used are: Zone 0: Explosive atmosphere for more than 1000h/yr. Zone 1: Explosive atmosphere for more than 10, but less than 1000 h/yr. Zone 2: Explosive atmosphere for less than 10h/yr, but still sufficiently likely as to require controls over ignition sources.
Zone 0 is an area in which an explosive atmosphere is present continuously for long periods of time or will frequently occur.
I was wondering about the origin of using the terms "number one" and "number two" for going to the bathroom (for those unaware, number one is urinating, number two is defecating, at least in the US). I have used it several times myself without actually thinking about it and heard plenty of others use it as well.
A jack and jill-style bathroom is a bathroom that connects two or more rooms. They typically come into play as a second full bathroom in a home for multiple people to share.
A 2.5 bath would mean two full bathrooms, and one half bathroom. A 1.75 bath would mean one full bathroom, and one three-quarter bathroom. A 1.5 bath would mean one full bathroom, and one half bathroom. And a 2.25 bath would be a full bathroom, a three-quarter bathroom, and a half bathroom.
With Jack and Jill bathroom suites, space is shared, or at least that's the idea behind it. A Jack and Jill Bathroom is a bathroom that has two doors and is usually accessible from two bedrooms.
NKBA designers recommend a 30″ clearance between the front edge of a fixture, such as a vanity or toilet, and any other fixture or wall. The building code allows for a minimum of 21″. The bathroom lavatory, or sink, should be placed far enough from a wall or shower wall that it's comfortable to use and easy to clean.
Most codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction and not closer than 30 inches center to center to any other sanitary fixture. (The NKBA actually recommends 32 inches.) There should be at least 24 inches of clear space in front of a toilet or bidet.
Even if the switch is not touched and exposed, electricity can still flow through from the electrical outlet through the water flowing down the wall to the floor onto which somebody could be standing. To protect against this, traditional light switches should not be installed in a bathroom.
This means for Zone 3: Zone 3: This zone has a minimum average of temperatures of -30°F to -40°F. Zone 3a: This subzone has a minimum average temperature of -35°F to -40° F. Zone 3b: This subzone has a minimum average temperature of -30° to -35°F.
Zone 3 is often called “Tempo,” and runs about 90-95% of your Lactate Threshold Heart Rate. Tempo means “the rate or speed of motion or activity; pace.” I still need to look up how this zone got this name, but to take a guess, it's the first zone where you feel like you are putting in some speed. LTHR. 140. 150.
Spend 80% of your cardio per week in Zone 2.
This is because Type I fibers use fat, and it is not until Zone 3 that your body starts to recruit Type II fibers, which utilize carbohydrates. This is why Zone 2 is KING!
These types of bathrooms do exist, and they are referred to as quarter-bathrooms. These quarter-bathrooms are quite rare simply due to the fact that they contain only one of the 4 main elements of a bathroom. The most commonly seen are those that contain a shower and are typically found at beaches or pools.
The short and simple answer to whether a walk-in shower is considered a full bath is “no”. It is not. As mentioned previously, a bathroom is considered a full bath only when it has all the 4 components of a sink, toilet, shower and bathtub. If it doesn't include all 4 features, then it doesn't count.
Named after the children in the famous nursery rhyme, a Jack and Jill bathroom is a full-sized bathroom that is sandwiched between two bedrooms and is accessible by both bedrooms. This type of bathroom has at least two doors, like an ensuite bathroom but for two bedrooms rather than just one.
