Ohm Electric Toilet Sound Masking Water Sound Generator 07-4850 OGH-2 Used for a short period. The surface and sides are in beautiful condition. I am selling this because a water sound generator came with the toilet when I remodeled it. ● For sound masking while using the toilet! For water conservation and cost-saving measures! ● Press the power button and the water sound will play for approximately 25 seconds. Press the power button again to stop the sound mid-way. ● Can be attached with double-sided tape. ● Volume can be adjusted in 2 levels. These are actual product photos. Thank you.
