Fans that may fit your needs are highlighted below.

Spruce remote-mounted inline bathroom fans operate in true silence. Their balanced design and high quality motors offer the latest technology in bathroom ventilation. Without proper ventilation, residual surface moisture builds up on bathroom walls, linens and carpeting. Moisture buildup can cause or increase allergy symptoms by encouraging the growth of mold, mildew, bacteria and dust mites. Moisture can also create structural damage by providing an ideal condition for insects and wood rot. For effective ventilation, bathroom exhaust points should be located over or near the shower and/or tub and in any enclosed toilet area. A Spruce inline fan is ideal for this purpose, as a single fan can be attached to multiple intake/exhaust points.
