Rain showers provide a warm, rain-like water coverage when you are showering, giving you a tropical raindrop sensation when you’re rinsing like underneath a waterfall, some call them rainfall shower heads or water fall shower heads. The heavy droplets of rainfall massage away the worries of the day and give you a perfect pick-me-up to begin or end your day with. Now you can get that rain shower feeling without the need to spend thousands of dollars with the Oasense Reva shower head. Reva indulges your senses while also making cost-effective water and energy savings for your home.
What is a rain shower head?
A rain shower is commonly accepted as being wider in size and larger in dimension than a standard shower head. Although there is no strict definition of how large a rain shower head needs to be, they are generally 5” or larger, and can be as large as 18”. Rain showers are usually seen as luxury showering experiences which can often be found in high-end Hotels and Spas as they provide an indulgent experience for the body and mind. This head-to-toe immersive showering experience is one of the many reasons why, despite the higher costs, rain showers are becoming immensely popular
What are typical Rain showers' flow rates and pressure like?
Rain showers can come as a stand-alone shower head or as a rain shower system, depending on the bathroom design. The shower will follow the same flow rate regulation as their peers' normal shower heads with the greatest flow rate allowed being 2.5 gpm nationwide, and the lowest flow rate depending upon different state or city regulations.[link] In the WaterSense certification program, rain shower heads are exempted from the center spray force mandate, which requested that shower heads have a minimum spray force at the center of 0.56 newtons at 20 psi to ensure shower quality.
It is not difficult to understand the reasoning behind this exemption. Once the shower head water coverage goes to 8” or above, the water flow is separated evenly into all the individual nozzles and which causes the water power to spread out. This results in weaker pressure on each nozzle, which is in contrast to smaller-sized shower heads where they can concentrate all the water out in a minimum amount of streams. However, since there are a lot more nozzles on a rain shower head than on a low-flow shower head, the water coverage is much higher.
Here we can see where the challenge in balancing the water coverage and spray force when there are flow rate limitations. Once the flow rate is limited, water coverage has to decrease in to get the same amount of pressure, or the product's water pressure will drop.
In the case of rain shower heads, they commonly rely on nature's gift, gravity, to compensate for the lower pressure. With a longer traveling distance and time from water droplet to body as rain showers are sometimes mounted higher, causing gravity to accelerate the water droplets that create the heavy rain sensation associated with rain showers.
If you’re looking to have a higher pressure rain shower, then it's probably best to look for a higher flow rate, smaller dimensions like 6” or 8”, or shower heads with different spray patterns if they are available. We recommend a 6” model like the Oasense Reva, which can act like a cross-over from shower heads and rain showers. as Oasense Reva is one of the higher pressure showers that pass the WaterSense spray force criteria and has enough coverage to be used as a rain shower. You can expect better water pressure than common rain showers from Reva.
Types of rain shower heads
Depending on the setup in your bathroom, the most common ways of mounting rain shower sets are as follows.
If you are remodeling a bathroom, plumbers can install a rain shower ceiling mount that has a water connection directly from the ceiling. This typically allows for a higher rainfall distance to achieve that drastic rainfall feeling.
A wall-mounted rain shower arm is an alternative to the high ceiling type. One can remove the old shower arm and install one of the rain head shower arms that has a 90-degree angle pointing downwards. Removing an old shower arm can be done by yourself. You just need to take more care at the joint because it's sometimes located behind the wall and hard to spot the leak. Take a tongue & groove plier, or self-adjusting plier, or “robogrip”, and carefully hold the base of the old shower arm, and rotate counterclockwise to remove the old shower arm and replace them with the rain shower style.
Rack, rain shower system
Some called this a European-style shower. For some older or non-wall mount-style plumbing systems, this type of shower system is sometimes used. A typical setup with an exposed vertical pipe can be found around the world, albeit less seen in the US. This also creates a rain shower sensation, and some models come with a handheld shower head with a hose and diverter so you can switch between a rain shower or a hand-held shower.
