A:Answer I bought a washer only and yes I had to pay extra for the water inlet hoses which were stainless steel braded hoses at $35.00, the installation was $24.99, The delivery was free and I paid for an extended 5 year warranty that I personally wanted for $130.00. The installation may be higher if they have to put the washer in some cofined area, upstairs or if the washer dementions don't fit your area. If your installation has issues that require inlet hose or drain hose modificarion. The washer dementions are 25 inches deep, 27 inches wide ,44 inches high with the lid down and 551/2 inches high with the lid up. Also they offered to move my old washer to another room or dispose of it for $34.00. I imagine they may offer some discount for the dryer/ washer combo install but be ready if they don't offer this.The dryer may need an outlet duct purchase and duct install and removal or moving dryer to another room. I can tell you that my personall experience with the dlivery and installation was very professional. They were knowledgeable and on time and before the actual delivery I was giveh a constant heads-up on their ptogress on the delivery.They did a great job.
