Fantastic Outlet Box!
[This review was collected as part of a promotion.] After using this washing machine outlet box, I’ve been extremely impressed! The first thing I love about this box is how quick and easy it was to install! The box easily fit into my small washing machine outlet box space. The unit is so compact! The next thing I really like about this washing machine outlet box is how the valves can be mounted on the top or bottom. This makes it easy to complete your project, regardless of what your setup is. Another great feature about this outlet box is how secure it is. The outlet box comes with brackets to prevent the outlet box from moving around. Another thing I’ve really liked is how tightly my pipes are sealed into the valves. I have not had any issues with the pipes becoming too loose either. Finally, I really love how durable the construction of this box is! The outlet box is constructed with very heavy-duty plastic, giving me the peace-of-mind that I will not have to replace my outlet box for quite some time! Overall, I’m very pleased with these outlet boxes. If you’ve been searching for a durable and dependable outlet box for your washing machine, look no further!

    Can be installed easily regardless of expertise!
    [This review was collected as part of a promotion.] I recently installed the Oatey® Centro II Washing Machine Outlet Boxes and it was extremely easy. The instructions were simple to follow and my washing machine room looks more organized. I only wish the kit came with the valves but all the other necessary components are included. I would definitely recommend this product especially to anyone looking to give their laundry room an organized look.

      Just this box itself is of a good quality, but I don't give it 5 stars because buying a box and valves separately don't make any sense to me price wise as it's cost about 20% higher if compare to complete box kit with valves. But there probably are situation when someone needs just a box so this one would be perfect for this kind of situation... Nice compact size, pretty durable, installs easily, we do make notches though to ensure our wallboard goes on flat.

      Well designed compact strong plastic. Best for 16” OC studs with access to back or new construction. Selected this washing machine box as replacement for existing hose bibs washer supply. Not able to use box as both sides of wall are finished and would require unanticipated sheetrock removal and repair. Other issue is drain is to be two feet above washer top, additional sheetrock removal and separated by a wall stud making connecting in box not possible. The Everbilt 1/2 in. brass MPT x MHT washing machine valves, type indicated for this compact box being over $15 each was an unexpected expense. An issue discovered on the product page online at HomeDepot.com while searching for a way to install box on finished wall. Despite not being able to currently install the Oatey Centuro box, it appears well designed for a clean recessed install. Box easily fits 16” but not 24” (brackets span 22 ½”) without additional support. Faceplate is adjustable for up to ⅝” sheetrock and has a nice smooth finish, ⅛” from wall. Instructions are basic and do not state box requires access from one side of wall, unless I’m missing something. Maybe not a big deal, but an unexpected aspect preventing the intended use in this DIY situation. Recommend the Oatey Centuro box for its strong plastic design and clean appearance despite it requiring too much renovation on a wall with both sides finished but that might be due to my inexperience with this model 38120 Oatey Centuro washing machine outlet box.

      I wasn’t too sure about the size of this product at first, I like my washer boxes to be taller than this one because the drain hose is usually stiff and tries to kink in tight areas. But I did find some compact color coded water valves that work well with this product. I did end up figuring out a better way to use this product for me, I installed a whole house water filter in combination with a tankless water heater for my garage and the box works great as just a water valve box and an access to get to fittings in my wall. I do also like the thickness of this product and the trim plate adjusts to different thickness walls.

      Preparing to convert part of our shop into an apartment for my elderly father (but not quite ready to install this yet). I like the smaller wall-print of this model instead of the bigger rectangular boxes. Commercial grade makes me feel even better about how it'll perform in my home; stronger PVC instead of cheap-o plastic. You can't install it upside down, because it has knockouts top and bottom. Includes support brackets. It should long outlast me with no problems.

      I requested this washing machine outlet box for our washer down in our basement. Although the washer has been hooked up for years with no issues, I am working on making the basement more finished in my free time and this outlet box is just the thing to make it look like a clean install as a recessed hookup behind drywall and foam board insulation. I just wish the outlet box was made with a more durable plastic and that it had a cover plate.

      Need to install an "IN WALL" water line for washer -HOT and COLD as well as the waste water pipe. This box comes with mounting straps and fits between the wall studs and thru the wall board. As I have not had time to install this one yet. It is of better plastic than the one I have used in the past. See pic. I like the fact that the waste water pipe fits in the middle of the 2 water valves.

      Oatey makes nice products and this is another one, versatile mounting options, small enough for a clean installation yet large enough to accommodate the supply lines and the drain. Designed to set flush with the finished wall for a nice looking / functional installation. Made of Plastic with glue on drain, pre-drilled for the supply lines and comes with two plastic / nylon retaining nuts. Very nice product that I highly recommend.

      The OATEY CENTRO plain washing machine outlet box is a well thought-out and functional piece of plumbing hardware. The knock-outs allow the plumber to not use any test balls during pressure testing of initial installations. The polystyrene construction feels strong as well as flexible. I really like the simplicity of the mounting brackets and since they are made of the flexible plastic can also be trimmed easily to fit a custom install. The flange has grooves which allow it to be literally clicked down until flush with wallboard. OATEY has been a go-to supplier of plumbing goods for as long as I can remember and I have never been disappointed with the quality of their products. Thanks!

      Ok , this is a basic Washing Machine box. New install or if you are replacing sheetrock will work too, Adjustable brackets for hanging between studs. Recessed with a snap in finish face plate. Knock out outlet for drain with proper sizing for drain pipes. I'm using this for a custom recessed box for a portable cart with a propane gas valve in the middle . This box works great for other uses for a nice box finish instead of boxing in with sheet rock strips and trying to mud and tape everything . FYI my box was in Spanish, limited instructions but if you have used this product or its like pretty self guided.

      This product really is a no brainer. If you are going to install a washing machine in a finished area like a laundry room, or even a basement that you want to finish you should install one of these with your plumbing rough-in. Easy to install - this product comes with some ears that allow you to position it within a stud bay. The box can be oriented for supply lines coming in from the top or bottom. The drain line has a knock out test cap in the event you need to test your DWV system. This model is the plain version without valves which gives you the flexibility to choose a valve style to your liking. Oatey makes and Home Depot sells several styles that include valves. I have included a photo of another model of this product that I have used which included the valves and hammer arrestors. In fact if you do not have valves already or do not plan to reuse the valves you have, you may want to consider one of the outlet boxes that comes with valves - just a better value.

                Exactly what we needed.
                [This review was collected as part of a promotion.] Exactly what we needed. The box the contractor installed was inside the wall, so the sheetrock was exposed, not attractive at all. I love that this has the lip on the outside, to hide the unsightly wall edges. Super easy to install, just slide into the existing hole and replace valves. Bright white color, includes the outlet box, face plate cover, and mounting brackets.

Anywho, I love the nice look this provides, looks so much better than the mess they had going on when we moved it! We are not super handy people, but we were able to install this easily! If you need assistance, I'd recommend looking up additional information on it, you can find some videos similar to what you need. All in all, I'm pleased with the look of my outlet area now!

The box itself is durable and well made. Note this is only for the plain box with the plastic faceplate and does not come with valves. The valves need to be purchased separately. I like that the faceplate is paintable and that the knockouts are located on the top and bottom to allow for additional mounting options.
